Available Services and Repairs for Dynamax Motorhomes
Your Dynamax motorhome is a high-performance machine built on a heavy-duty chassis. It requires a service facility with the tools and expertise to match. We provide comprehensive chassis service for your Freightliner M2, Ram 5500, Ford E-Series, or Mercedes-Benz Sprinter chassis.
Preventative Maintenance
This is the most critical service for protecting your investment. We follow the chassis-specific maintenance schedules for your Dynamax, including all routine oil and filter changes for diesel or gas engines, fuel-water separator service, air filter replacements, chassis lubrication, transmission fluid exchanges, and coolant flushes. We also top off Diesel Exhaust Fluid (DEF) as needed.
Brake System Repairs
Given the high gross vehicle weight of the Dynamax lineup, we provide expert brake service. We are fully equipped to diagnose and repair the full air brake systems on Freightliner chassis, including servicing air dryers and gladhands, as well as the heavy-duty hydraulic disc brake systems on the Ram 5500 and Ford E-450 platforms.
Engine and Transmission Services
This service goes beyond basic maintenance. We perform advanced diagnostics for “Check Engine” light issues and performance problems like power loss or rough idling. We specialize in servicing the Cummins diesel engines and the heavy-duty Allison automatic transmissions in your Super C, handling all mechanical repairs from the fuel system to the turbocharger.
Suspension and Steering System Maintenance
A Super C chassis requires a precise setup for safe handling. Our state-of-the-art heavy-duty alignment rack can handle your Dynamax to stop steering “wander.” We also service all air ride suspension components, leaf springs, steering boxes, and kingpins to ensure your coach is stable, comfortable, and tracks straight.
Cooling System Maintenance
A heavy-duty diesel engine under load generates massive heat. We service the entire cooling “stack,” including the radiator, charge air cooler (CAC), and hydraulic cooling fans. Our repair services include replacing water pumps, thermostats, and serpentine belts to ensure your engine is protected from overheating.
Electrical System Diagnostics and Repairs
We specialize in the complex 12-volt chassis electrical systems on your Dynamax. We can troubleshoot and repair any issue with your starting and charging systems (chassis batteries, alternator, starter), multiplex wiring issues, and all factory-installed lighting and dash-mounted controls.
Note: We do not service the 120V “house” electrical system.
Exhaust System Repairs
We service the entire heavy-duty exhaust system from the engine block to the tailpipe. This includes repairing exhaust manifold leaks, replacing damaged piping or mufflers, and servicing the engine’s “Jake brake” or exhaust brake. We ensure your system is leak-free, quiet, and performing efficiently.
Tire Services
The tires on your Dynamax are critical, load-bearing components. We inspect all tires (including inner duals) for proper inflation, wear patterns, and age-related sidewall cracking. Our heavy-duty equipment is designed to handle the precision spin balancing, rotation, and replacement of large 19.5-inch and 22.5-inch wheels.
DEF System Maintenance (for Diesel Engines)
A functional Diesel Exhaust Fluid (DEF) system is essential for every modern diesel chassis. This service focuses on repair. We provide complete diagnostics for DEF-related warning lights and derate conditions. We can test and replace failed DEF heaters, pumps, and sensors to get your engine back to full power.
