Keep Your Diesel Coach Running at Full Power
Diesel motorhomes fall through the cracks. RV dealers look after the house and won't touch the chassis; truck shops aren't set up for a forty-foot coach. We do both. Whether it's a derate code, a regen that never completes, a blown turbo or an air leak that drops the coach overnight, our mobile technicians bring dealership-level diagnostics to your campsite, storage lot or driveway — Cummins power on Freightliner and Spartan chassis.
What We Offer
Installations & repairs.
A check-engine light on a coach can be anything from a lazy sensor to an impending derate that will strand you halfway up a grade. We bring dealership-level diagnostics to where you're parked and read the chassis, not just the dash — Cummins ISB, ISL and ISX, Allison transmission faults, and the Freightliner or Spartan chassis underneath.
Why Blue Summit
Chassis and Coach, One Call
Diesel runs in our blood — and we know a motorhome is not a truck. It's a house on a heavy chassis, and it has to bring your family home.
We work the chassis side most RV shops send away: Cummins ISB, ISL and ISX power, Allison transmissions, Freightliner and Spartan chassis, air brakes and air suspension, aftertreatment faults, and the Onan generator nobody thinks about until it's needed.
Coaches don't fail the way trucks do. They sit for months, then run short trips at low load — the exact duty cycle that keeps a regen from finishing, flattens batteries and dries out seals. A lot of what looks like an engine problem is really a duty-cycle problem, and knowing the difference is what saves you a tow.
We move fast, tell you plainly what we found, and stand behind the work. Your season should be spent on the road, not waiting on a service bay.
