RV Trailer Supply is an RV parts store and repair shop based in El Cajon, California. You bring the RV to them, and they work on it at their location on Broadway.

They handle appliance repair, electrical systems, and installation of refrigerators, awnings, solar systems, satellite systems, water systems and more, on motorhomes, towing cargo trailers, toy haulers, flatbed trailers, box trailers and motorcycle trailers. On the trailer repair side they do wheel pack, brake replacement, wiring and towing set-up work. They also handle RV trailer rental and fleet repairs, including inspections, for anyone leasing a personal RV or trailer. Alongside repair, they stock a large inventory of name brand parts, including Dometic, Norcold, Suburban, Carefree and Atwood, and say if they don't have a part, they can get it. That matters if your rig uses an older or obsolete part a big box store won't carry. Their service area covers El Cajon, San Diego, Chula Vista, La Mesa, Santee, Poway, Escondido, Oceanside, Vista and the surrounding areas.

No hourly rate, trip fee or diagnostic fee is published, so ask about cost when you call. Hours run Monday through Friday 8:30 am to 5:00 pm and Saturday 9:00 am to 2:00 pm, closed Sunday.

The business has been family owned since 1971, which is a long run for a parts and repair shop to stay in one spot. Google rates them 4.6 stars from 273 reviews.

This is a good fit for an owner in the San Diego area who needs a specific appliance or part sourced and installed, or who has a rental or fleet trailer that needs repair at a shop rather than on site.
