It's a great rig. When I bought it, if it had an option, "It's on there". Contact me for a detailed list.The rig is still on a transferable extended warranty. I will also transfer a lifetime Thousand Trails membership. Special features:  I retained a BluTEC engine expert for advice prior to purchase. In accordance with his advice, I installed an Optimate 6 trickle charger, as well as a catch tank (SEPR8R Air Oil Separator). I also have a stack of “insider” Mercedes Benz service materials on that engine that he gave me. Following his advice, I have babied this rig by to using -despite its expense— Marvel's Magic Mystery Oil additive every refueling, and BG 245, every 3rd fueling. I also have had the oil changed every 5000 miles rather than the 15,000 mi recommendation from Mercedes. At the rear, is a custom-designed (by me!) spacious rear rack, that holds a lounger and 2 tables with custom canvas covers. It also has a dual-receptacle tow hitch that accommodates both the rack as well as a tow bar. All of these are included. I had a cell phone booster installed, although a tree knocked the cover off. I have a new one, but have never installed it. It also has a Winterizer kit for the Insta-Hot water. The rig has an exterior propane valve, and there is a nice BBQ unit (never used), that will go with the unit.
