Trusted Motorhome Repair Services

Your RV or camper is more than just a vehicle—it’s your home on wheels. Keeping it in top condition is crucial for safety, comfort, and performance. Our team specializes in motorhome repair and RV maintenance, offering comprehensive services to keep your Class A, B, or C RV in peak condition.

RV & Motorhome Diagnostic Services

Motorhomes combine heavy vehicle systems with additional electrical loads and equipment, which can make some problems harder to trace. Accurate diagnostics help identify the source of the issue before parts are replaced or additional repairs are recommended.

Our RV diagnostic services can help identify:

  • Engine Performance Problems: Diagnose warning lights, power loss, hard starting, rough operation, and other engine-related concerns.
  • Electrical Faults: Test batteries, charging systems, wiring, connections, and related electrical components.
  • Cooling System Problems: Find the source of overheating, coolant loss, and temperature-control issues.
  • Starting & Charging Issues: Determine whether a no-start or weak-start condition is related to the battery, starter, alternator, or electrical system.
  • Ride & Handling Concerns: Inspect steering and suspension components when the motorhome pulls, wanders, vibrates, or handles differently than normal.
  • Brake System Problems: Evaluate braking concerns before worn or damaged components affect safe operation.

A proper diagnosis gives RV owners a clearer repair plan and helps avoid replacing components based only on symptoms.

Signs Your Motorhome Needs Mechanical Repair

Changes in performance, handling, temperature, or electrical operation can indicate a developing mechanical problem. Having the RV inspected early can help identify the cause before the issue leads to more extensive repairs or interrupts a trip.

Common warning signs include:

  • Loss of Engine Power: The motorhome struggles under load, accelerates poorly, or no longer performs normally.
  • Frequent Overheating: Rising engine temperatures or coolant loss can point to a cooling system problem.
  • Hard Starting: Slow cranking, intermittent starting, or repeated battery issues may indicate a starting or charging fault.
  • Steering or Handling Changes: Pulling, wandering, vibration, or excessive movement can signal steering or suspension wear.
  • Unusual Brake Response: Changes in stopping distance, brake feel, or air system operation should be inspected promptly.
  • Electrical Problems: Flickering lights, battery drain, warning lights, or intermittent electrical failures can indicate wiring or charging issues.
  • Unusual Noise or Vibration: New sounds or movement may point to worn chassis, drivetrain, suspension, or engine components.

I called 23 different companies for help with a stranded truck, and Amoretti Diesel were the only ones able to assist. After spending nearly six hours on the phone trying to find help, I finally called Amoretti. Within 25 minutes of ending the call, they had my truck back on the road. Exceptional service when I needed it most.

Our pneumatic lines on our class A coach kept melting and bursting.   They got us in immediately, found a spot that the turbo wasn't connected to the exhaust due to a loose clamp.   They got a new part, welded it on, rewrapped all the wires who's protective mesh had melted and sent us on our way.   Incredibly knowledgeable and so kind.  Could not be happier with their work.
