"I was routed to them after my dealership refused to send someone to my RV and honestly it was simple, upfront, priced well. and I look forward to contacting them again should the need arise!"
"Christian gave us a very competitive price. He was very helpful in showing me some of the maintenance items I need to look out for in the future. They performed quality work at reasonable pricing. I highly recommend them."
"Christian was excellent all-round! Very professional, knowledgeable, considerate, and well organized. His service vehicle reflected all of these attributes (clean, organized, stocked,etc.), his pride in his work / company was then further enhanced by customer interaction skills, and then proven via his mechanical skills. His response time was amazing from start to finish (return of initial inquiry call, quote, and scheduling). All of the above allowed my family to start our winter trip north with no stress."
"Called for fridge repair a few days before we were supposed to leave. It needed parts, and they had to be shipped. He managed to get us on the road with a delay of only one day!Impressive!"
"Hands down the best RV repair company. Christian stands by his work and goes above and beyond. Infinite RV is now my only go-to for all my RV service and repair needs!"
"Christian is great and he knows RV's. He installed a Starlink, Kenwood carplay and braking system for a flat towed vehicle. Christian explained how everything works and gave additional advice about hooking a flat tow vehicle."
"Very good communication. CJ did a very nice job installing some mods to my sprinter camper. Highly recommended."
"I asked Christian to install actuators under my bed to easily access the storage underneath it, in my RV. First, he met me to measure prior to ordering any parts. At this meeting I could tell he was very thorough about getting this right. After the parts arrived, less than a week later, he came to do the install. I could not be HAPPIER with the job! He was prompt, clean, focused, reasonable, respectful and performed this task beyond my expectations."
"CJ was honest and straight forward on his pricing and what needed to be done. He was able to do quality work at a fair price. I would highly recommend calling him to help you with your trailer needs."
"My dealer I was using shut down. I found Christian here on yelp and contacted him for a quote on fixing a airbag on my rv. He came out quick and gave me a quote to fix it. Price was fair and he did a great job. I would definitely recommend Infinite Rv and I have my new go to for RV repairs."
"The service is excellent . Christian fixed what is necessary. Promptly and professional. Price is reasonable. I would use his service for any repair in the future"

"They did an amazing job on my trailer's maintenance and they have great customer service! I would recommend them for service and would definitely have them come by and do it all over again!! Thank you!!"
"He solved the electrical problem on my 2022 Airstream Caravel. He has a great knowledge and did proper work. I'm happy with the service and highly recommended !"
"If you're looking for someone to work on your RV look no further. Infinite Rv does great work, is dependable and does a great job at troubleshooting! Very pleased with everything he's done for my RV."
"I tore up my awning and dinged another trailer while doing it!!! Christian made two trips to where we have the trailer stored. On the first he got half of the awning out of the way. He then ordered parts for the other trailer and half of the awning support for me. When the parts came, we made an appointment and met him at the storage yard. He was already there and working on the other trailer when we arrived. Then he worked on our trailer. When he had finished, you couldn't tell anything had happened. His charges were inexpensive too! I'll be calling him again soon!"
"CJ is a great dude, that took care of the AC issue on my Airstream in a timely manner. Communication was great! Pricing was a little steep, but these things aren't cheap! I am happy with the service and would definitely use his services again!"
"Generator wasn't working and we needed to replace the carburetor. CJ offered a new OEM for list price (no markup) or rebuilt for about half the price of new - both were in his truck. After hearing about the pros/cons, I decided to have the new one installed and it runs great. CJ is responsive, honest, friendly, and good at what he does, all at a fair price."
"Contacted Christian about concern with no exterior lights on my RV. Came out on time and within 75 mins had found problem, fixed concern and also answered some questions we had about other parts of unit. He was very polite and took time to answer our questions. We will definitely be using him for more repairs once I get smog cert and other minor things to get unit back on the road. Great service overall !!"
"Received great service. Prompt response, on time. I needed a new window in my door and a sink rand faucet replacement. I had already purchased the parts and Christian installed the window and redid plumbing for the sink/ faucet install. Work was top notch and price was fair. This company is my go to for any work on my rv. Highly recommend."
"I called. Kevin spoke with him. Seems like a very nice guy very informative and helpful. It was trying to help me to save money to take care of project. I've been trying to take care of for a while. Highly recommend him."
"First time using Infinite and CJ was great to communicate with. He texted back with specific questions before scheduling our appointment, to be sure we both agreed with the work to be done. He ordered a part ahead of time (checking first to see if I agreed with the order and pricing). He took time to show me what the issue was and fixed it quickly at a price much better than the dealer I had been using. CJ even took the time to answer a few more questions once he finished the job. I plan to use Infinite again, as needed. Great first impression."
"Great experiencing working with CJ. He is always available to call if you have questions. Being mobile really helped my situation too as I was only in town for a limited time and needed some assistance. His work is very good"
"CJ was really helpful in repairing our trailer brakes on my pop-up trailer after they stopped working. We had a trip coming up quickly, and he was able to come out right away. Once he diagnosed the problem (worn brakes plus a wiring issue), he ordered the parts and worked with me to come back and finish the repair prior to our trip. The brakes now work flawlessly. I highly recommend Infinite Mobile for your RV repairs."
"I was very happy receiving prior notice that Christian was on his way. He was prompt with the appointment time. He serviced my unit and addressed a couple other concerns which really made big difference! I will definitely recommend his service to family and friends with RVs needing honest and competent help!!! Thank you thank you so much!"
"CJ is top notch service!I asked for a quote for axle repack plus an overall inspection of my trailer, agreed on day and he came and delivered just as he said he would. Pricing is right and fair. He explained what he did, what he saw and some notes regarding the status of my trailer, plain and simple.I highly recommend him for anything RV, thank you CJ!"
"Very happy I went with this place. Had a battery explode in my rv and I wanted it fixed as soon as possible. I called multiple rv repair mechanics and this was most reasonable. He was honest about the price and gave honest recommendations. It was just two battery replacements but the area was cleaned and left neatly. The communication was great. I would definitely contact this place for future rv repairs."
"I had my motorhome at Camping World to check my inverter as it was faulting with an "over temp" on the display. I could not hear any fans coming on when it would fault and shut off power to the coach. The power would resume once it cooled off. Camping World's diagnostics came back I need a new inverter with a price tag over $3,200. The service advisor upon questioning him said these inverters cannot be fixed and I need to replace it. I decided to bring my motorhome home and I tested the inverter. It was not damaged and still was working. I called and spoke with a tech at Fleetwood that said I should be able to replace the fans. It was also pointed out at Camping World that someone put an aftermarket temperature sensor on, so I decided to buy a factory MAGNUM temperature sensor. I decided to use Cj as he has such good reviews. I am over thrilled I went with my gut and and bought the fans, temperature sensor and had Cj install the new parts. We plugged in the motorhome and it has been working like a charm. Between parts and labor I spent about $580 verses the $3,200 Camping World wanted to charge me. Will definitely use Cj again and will recommend him."
"Excellent service. Replaced the motor and gear box on our slide. The whole job was done in a few days and that included ordering the parts. We were on the way the next day and have had no issues with the slide. Everything works great. I will definitely use Infinite RV Mobile again.Steve"
"CJ was very polite and professional. He changed the even window very quickly and did a great job. Thanks CJ!"
"CJ helped us with our motorhome wiring. We had some issues with the wiring. He was able to find and fix them all. We will definitely call him next time we have a problem. Thanks CJ"
"I see why Infinite RV Service has so many 5 star reviews, they earn them.CJ installed a Wingard router in my 5th wheel. On time for a fair price.Very neatly installed and he made sure it worked to my satisfaction before leaving.He also inspected my roof for free while he was on site.I will definitely keep his contact information close by."
"From electrical, to plumbing, control panels, and over all workings of our 5 wheel, CJ really knows his stuff. He walked us through every aspect, and gave us the confidence to start our permanent vacation. I highly recommend him for All your trailer /rv needs or concerns. Go ahead, give CJ a call. You won't be disappointed. Sincerely,Sammy and Aly."
"Everything about our service with CJ was incredible. He replied to me as soon as I reached out with the request and was straightforward with all his pricing and explanations. CJ was able to source the materials needed for our project directly from Tiffin and communicated with me every step of the way. He was so flexible and helpful and you can tell that he genuinely cares about the work he does. We needed the ceiling paneling replaced due to damage from a leak and he was so meticulous with his work and went above and beyond to make it blend. He installed our Starlink and explained all of the rewiring and took the time to make sure we understood the system before he left. I am so glad that we found CJ and Infinite RV Repair!"
"Amazing! Came all the way from OC to LA to help me with a minor problem. Told me pricing upfront, & I didn't have to wait 2 weeks like I would have with other large companies, drove to my location so i didnt have to haul my 33ft rv over and help fix my problem. Nice guy, helped me with another small problem over the phone too after. Needless to say, I have his number saved as my rv guy now! Thank you!"
"All the outlets on my travel trailer stopped working a day before our trip. All the major facilities were full and could not take us in. We found Infinite RV on yelp and loved the reviews. He came out in a days notice and figured out the issue the same day. CJ was great and even worked with our extended service contract. Got the approval and got me my refund for the service call while I was on my trip. Highly recommend their service."
"CJ was quick to respond, helpful over the phone and wanted to help us if he could. We were packed up and ready to leave for a 2 month trip and lost all power to operate the slides and jacks on our 5th wheel. We searched Yelp for a mobile RV tech and called Infinite RV at 12:30 pm. CJ answered right away, asked us a few questions and for a couple of photos then gave us an idea of what it could be. When we told him of our urgency, he confirmed that he could be out to our house at 6:30 pm THAT SAME DAY. On his way, he texted his time of arrival and got to us on time. He spent about 25 minutes checking out our RV batteries and our truck's electrical hookup and found issues with both. He spent time troubleshooting and sharing his expertise, and although he didn't end up doing any repairs, we would recommend Infinite RV Mobile Service for a fair, responsive and knowledgeable RV tech service."
"CJ was on point. He responded very quickly. Diagnosed my issue right over the phone and went over a couple options with me. Fit me into his schedule the same week and resolved my issue for a fair price. And he even gave me a complimentary walk through of my unit as I didn't know as much as I thought I did. Definitely going to use him from here on out."
"Due to the recent downpour of rain I noticed my coach was leaking. I reached out to Infinite RV and CJ the owner responded promptly with a reasonable quote to reseal roof. He fit me into his schedule very last minute when most dealers and shops had turned me down. He performed the task very quickly and it turned out beautifully. Soon after that I reached out for a solar install and that is when his real expertise kicked in. He gave me a variety of options and ideas. Once I decided once again he was very quick and detailed. Took the hassle out of getting me coach serviced. Super convenient and excellent work! Thanks again CJ. Look forward to working with you in the future."
"Chris came out on a moments notice to check out the slide issue. He was able to locate and fix the problem. I'll definitely call Chris again."
"We were camping in our RV when the CO/Propane detector went off in the middle of the night. So we got up, opened the windows and doors and the alarm went silent. But since we didn't know the issue, we turned off the propane and spent the remainder of the night without heat. It was 34 degrees outside! When we got back home I started looking for repairmen. The dealers seemed too expensive. I found Infinite RV Repair on YELP and requested a quote. Chris and I initiated a dialogue and he was very responsive and complete in his answers. Within a couple days he came out and diagnosed the problem - a defective regulator coming off the external propane tank. He ordered the part and installed the new regulator 2 days later. He performed the "drop test" and it was still leaking, downstream from the repair he had made. He ordered a 2nd part and that fixed the problem. During the process, he communicated frequently and clearly. While he was here, he explained exactly what he was doing to we could follow along. He charged a fair price. I highly recommend this knowledgeable repairman for any RV repairs!!"
"Chris is super legit!! Very knowledgeable at what he does and gets the job done quick!!!Thanks Chris..."
"I'm a new owner of a 20 year old class A motor home. After I brought it to SoCal, I noticed the Agua Hot on demand water heater's burner system wasn't working. The electric side of the system did, however the diesel burning side wasn't. In the cold, it can't heat the interior to well or supply hot water for more than 20 seconds. I searched Yelp and found Infinite RV Mobile Service with good reviews. I text CJ if he worked on Agua Hots. He said he had and came out to the RV park I was visiting. He checked it out and decided to do the annual recommended maintenance on it first, which is replacing the fuel nozzle and fuel filter. He ordered the parts which weren't expected for a week. Having been in the RV repair business for a while, he contacted a couple of repair friends in the business to see if they had the needed parts laying around. Lucky enough, he found the nozzle and fuel filter and came back out two days later. He replaced the parts and still not working. He performed a diagnostic on the burner unit and was able to narrow it down to being the ignition module. He also called Agua Hot and got more information on what else might be happening from their techs. He checkout the other "easier" solutions to no avail. I ordered the ignition module from Amazon which came a few days later. CJ squeezed me into his schedule and installed the igniter which fixed my problem. Immediate hot water for showers and the cabin heater works well. CJ was always up front, honest, resourceful, on time, did his research and didn't waste his time which was money saved for me. I've since gotten estimates from him on other items I'd like to add on eventually. I highly recommend Infinite for any non-chassis related RV repair. I'll definitely have CJ do any future repairs."
"CJ was great to work with. Knowledgeable, responsive, quality work, good price, etc. Even worked with my warranty company. Will use again for sure"
"I recommend CJ and his business. The entire experience was outstanding. The initial contact on Yelp, the discussion of what I need to have done, the professional bid and the confirmation of services was thorough and appropriate.When CJ arrived at the campground where I am staying, he was friendly and got right to work. I had many questions and some things I just had not had enough experience and he took the time to explain and share his knowledge and experience as well as made recommendations.I have a Class C. CJ has a very keen eye on servicing the engine, generator, safety (gas LP testing, and tire pressure), and maintenance of the roof and vents, awning and even the water system and toilet! The personal and professional service is above and beyond many of the service and repair places I have encountered. CJ came and accomplished the work. I am grateful for such an experience and hope to call him again whenever I am in town as I feel the level of service and satisfaction are top notch! I feel more confident with my rig as no YouTube video or Manual has provided me with the knowledge and level of confidence that I gained today!Thank you!"
"Wow, CJ was amazing! We are complete newbies and he was patient and walked us thru so much! Keep up the great job, we will use him for all our RV Trailer needs!"
"I'll start by saying Chris is GREAT! I'm a newbie to the RV life and needed a T4 and wifi installed. First off I had no clue of what I actually needed and didn't need. Chris took my call before hand and clearly explained to me what was needed, and what wasn't. I appreciated that he didn't try to up-sale me on anything, and upon inspecting my rig, realized I was more equipped than I thought, and advised me of it, therefore decreased my price as he didn't have to do as much work. He definitely could've taken advantage of my lack of knowledge, but didn't at all. He was personable, knowledgeable, and worked diligently to complete the job. After installing the devices, he helped me set them up and answered each question I had. I know I had gotten on his nerves, but he was patient with me! Thanks Chris! I'll be calling you in the future."
"I am so glad we found Infinite RV to finally fix our Trailer's air condition and roof leak issue. Highly dependable, with great communication, very easy to work with, and CJ is very knowledgeable. We have several RVs and Trailers that sometimes are in need of emergency repair. It is very difficult to find a business that is capable of fixing a problem efficiently. Infinite RV was able to fix a major repair that has been plaguing our mobile Trailer in 2 visits. CJ is very detailed in explaining the structural, mechanical, and electrical issues and clearly explained how he will fix the problem. An absolute professional. My only wish was I hope we would have found Infinite RV sooner."
