2006(2007 build) Pleasure-way Plateau TS. About 55K miles on it. 15K miles since I bought from Original owner. NO problems. I-5 engine is trouble-free. Only problem was turbo resonator(replaced at 12K). Get 30MPG(26US), regularly. Service by Mercedes dealer here. About 200$ oil(synthetic) & filter. Interior is squeak-free(maple wood) and shows very little wear--better shape than driver!
Strong brakes and remarkable turning circle on 144 (21ft11ins) chassis model.
Use Gearspace 34cuft cargo carrier on hitch.
PS I don't experience any "sway" with mine. Have airbags on back and keep rear at 80 and front 55 so no oversteer. My 2 previous Ford(rvs) wandered all over the road,especially in winds.
cheers
