You may not be able to see the Maxum Chassis as you’re driving through the Rockies, but you’ll know it’s there. Its powerful Cummins turbo-charged diesel engine and Allison® transmission go to work so you don’t have to sweat the peaks and valleys ahead. 

Through a strong partnership with Freightliner, the undisputed leader in diesel motorhome chassis, we set a new standard for handling, ride and performance in diesel chassis design.

But performance doesn’t mean sacrificing storage. The innovative lowered-rail design of the Maxum Chassis opens up a cavernous basement storage compartment, offering up to 196 cubic feet of storage.
