You will have everything you need to prepare your best meals including a countertop extension. Enjoy your meals, play card games, and even transform into a sleeping space all with the Dream Dinette. The tri-fold sofa sleeper not only has seatbelts for traveling, but also can transform into a sleeping space too. You can also choose to add the optional bunk over cab for more sleeping space or switch out the sofa for the optional theaters seats!
You will have the perfect combination of brute force and refined living with each one of these Dynamax DynaQuest XL Super C diesel motorhomes! A Freightliner M2 112 chassis holds these units together, a Cummins L9 turbo diesel engine with 450 HP powers them, and twin 50 gallon aluminum fuel tanks help them go farther. An Equiflo inboard fuel system creates dual supply and dual return, and the diesel Aqua Hot 450D system provides continuous hot water, as well as preheats the engine. The seamless, easy-clean rotocast storage compartments have LED lighting for you to see at night and remote locking doors. A few other features you will appreciate include a water filtration system, multiplex wiring with a touch screen command center with Bluetooth phone app control, and an exterior shower in the service bay to keep the dirt outside where it belongs. Come see all of the many luxurious features that will make every one of your trips comfortable and fun!
