Jefe's RV Service is an RV repair shop based in Commerce City, Colorado. You bring the RV to its shop for appliance work, and it says to "Call now to schedule your appliance repair in our shop," so plan on bringing the rig in rather than expecting a visit.
It works on motorhomes, travel trailers and fifth wheels of all makes, covering electrical systems, plumbing, appliances (refrigerator, furnace, air conditioning, water heater, stove), structural and exterior repairs, slide-outs, leveling systems, solar panel installation and repair, generators, wheel bearings, axles, awnings, and winterization and de-winterization. It services major brands including Coleman, General Electric, Dometic, Winnebago, Airstream, Grand Design and Newmar. It serves Denver and the surrounding area, naming Arvada, Broomfield, Thornton, Denver, Aurora and Commerce City.
No trip fee, hourly rate or diagnostic fee is published, so ask about cost when you call. There's also no listed hours of operation or after-hours service, so confirm scheduling on the phone.
The shop has been at it for over 15 years, run by owner Jeff Ramos, who has almost 20 years in the RV and trailer repair trade. It also offers pre-purchase inspections, worth asking about before buying a used rig so you know what you're taking on. It says it honors "most extended warranties" for covered repairs, and its wheel bearing service includes new grease, seals, dust caps and a brake adjustment, which matters since the page notes manufacturers recommend that service every 2 years, or 10k miles, whichever comes first. Google rates it 4.9 stars from 196 reviews.
This is a good fit for an owner in the Denver metro area who wants a shop visit rather than a mobile tech, especially for appliance repair, hail damage, axle work or a pre-purchase inspection on a used RV.
