RV Repair & Maintenance in Oxnard, CA
A motorhome is a house sitting on a truck chassis — and the truck half is where trouble usually starts. Bring us the mechanical side of your RV for ASE-certified work at discounted RV labor rates.

We handle the part that gets you there — and stops you
Most RV trouble starts under the coach, not inside it. Engines that overheat on a long grade, transmissions that slip when loaded, brakes that fade, a generator that won't charge, dash air that quits on a hot day inland. Dieter's Motors has diagnosed engines, brakes, drivetrains and electrical systems in Oxnard since 1972, and we bring the same factory-level tools and ASE-certified technicians to motorhomes. Owners from Oxnard, Camarillo, Ventura, Port Hueneme and the Channel Islands Harbor area bring us coaches that need the running gear sorted out before the next trip.
We work on Class A, B and C coaches on gas and diesel chassis, from van-based Class B campers to diesel pushers, along with tow vehicles, trailers and truck campers. A pre-trip inspection before a long haul — or a post-storage check after months parked near the coastal salt air — catches leaks, worn belts and hoses, brake wear and cooling problems before they strand you. Call ahead, since RV-sized space is limited, and we'll have a bay and a technician ready.
We'll be straight about scope: we focus on mechanical and chassis systems, not coach interiors, cabinetry, plumbing, roofs or body work. If it isn't ours, we'll say so. For heavier diesel engine work see our diesel repair page, and for stopping power on a heavy coach, our brake repair team.
Everything under the coach
Factory-level diagnostics and heavy-duty repair for the running gear — gas or diesel, motorhome or tow vehicle.
Engine & Transmission
Engine, transmission, differential and driveline service on common RV chassis, from Class C vans to diesel pushers.
Brakes & Hydraulics
Pads, rotors, drums, calipers, hoses and fluid — specified for the real loaded weight of your coach.
Suspension & Steering
Shocks, bushings, front-end wear and sway control so a long day of driving stops feeling like work.
Charging & Generator
Alternators, batteries, isolators, onboard generator service and charging faults traced properly, not guessed at.
Dash A/C & 12V Electrical
Dash air that blows cold, no-start diagnosis, 12V gremlins, lighting and chassis wiring repair.
Pre-Trip Inspection
A full mechanical once-over before a long trip or after storage — fluids, belts, hoses, brakes, cooling, leaks and tires.

How do your discounted RV rates work?
RV mechanical repair and maintenance is quoted at a reduced labor rate compared with our standard rate. Mention it when you call and we will include the discounted figure with your estimate before any work starts, so there are no surprises when you pick up the coach.
Do you work on diesel pushers as well as gas motorhomes?
Yes. We service both gas and diesel RV chassis, from van-based Class B campers and Class C coaches to Class A diesel pushers. Call with the year, chassis and engine so we can confirm the work and make sure we have space for your coach.
Do you fix RV interiors, plumbing or roof leaks?
No. We focus on mechanical and chassis systems, not coach interiors, cabinetry, plumbing, roofs or body work. If your problem falls outside our scope, we will tell you on the phone so you do not waste a trip, and you can bring the coach to us for the running-gear side.
Do I need an appointment for RV service?
Yes, please call ahead. RV-sized space is limited, and scheduling makes sure there is a spot and a technician ready when you arrive. We are open Monday through Friday 8am to 5pm and Saturday 9am to 1pm at 2681 Ventura Blvd in Oxnard.
Can you inspect my RV before a road trip?
Yes. A pre-trip mechanical inspection covers fluids, belts, hoses, brakes, cooling system, leaks, tires and charging, and it is a good idea after long storage too. We tell you what needs attention now and what can wait, with a written estimate at our discounted RV rate.
