On-Site Mechanic

On-Site Mechanic is a mobile truck and equipment repair business based in Boulder, Colorado. It comes to you, whether that is a job site, a truck stop, a warehouse, your home, or the side of the road, so there is no need to tow anything in.

Its main work is light, medium, and heavy-duty trucks and construction equipment, but it lists RVs and trailers among the vehicles it services, along with semi-trucks, box trucks, flatbeds, and heavy-duty diesel pickups. On the RV side, the kind of work it describes doing on-site includes brake work, electrical and battery issues, cooling system fixes, starters and alternators, oil changes, and engine diagnostics. It covers Boulder and the surrounding area within roughly 10 miles.

No hourly rate or flat prices are published. "There may be a service call or trip fee to cover travel, which we'll explain when you book," so ask about that cost when you call. It also offers emergency and after-hours roadside repair, though availability and after-hours rates can vary, so call its dispatch line to find out how soon it can reach you.

It is family-owned, with a background in the construction industry dating back to 2013 and 8 years of diesel and fleet maintenance experience. Google rates it 5 stars from 38 reviews.

This is a good fit for a traveler whose RV or trailer breaks down within Boulder's immediate area and needs a mechanic to come to them rather than find a tow, particularly for mechanical, electrical, or brake issues rather than RV-specific systems like appliances or slide-outs.
