Describe the problem once — by chat or one phone call — and nearby mechanics bid back with exact price and ETA. You pick, they roll, payment settles through RIG when you're moving again. No phone-book roulette, no blank-check invoices, in Denver or 2,000 miles from it. And it's not just semis: the network serves commercial diesel of every kind — semi trucks and trailers, motor coaches and buses, RVs, box trucks, and heavy equipment.
“Altitude, grades, and winter — Denver is hard on trucks and harder on schedules. A perfect thumbs-up record here means more than it would almost anywhere else.”
“The grades into Denver cook brakes and derate engines all winter. A perfect satisfaction score up here is the hardest stat in our network.”
Fixed roadside, not towed
What mobile mechanics actually fix at the truck
Most breakdowns never need a tow. These are the jobs RIG dispatches every day in Denver and across the network — on semis and trailers, motor coaches, RVs, box trucks, and heavy equipment — handled on the shoulder, at the truck stop, or in the receiver's lot:
Tires & wheels
Blowouts, roadside tire changes, wheel seals, hub and bearing repairs — the #1 call we dispatch.
Air system & brakes
Blown air lines and glad hands, leaking brake chambers, air bags, slack adjusters, ABS faults.
Electrical & no-starts
Dead batteries and jump starts, starters, alternators, wiring shorts, marker and headlight fixes.
Cooling system
Coolant leaks, radiator and water pump swaps, blown hoses, antifreeze top-offs before damage is done.
Aftertreatment & derates
Forced DPF regens, DEF system faults, EGR issues, limp-mode derates cleared at the truck.
Driveline & engine
Belts, fuel filters and injectors, turbos, clutches — plus reefer units, liftgates and landing gear on the trailer.
