we,ve had a sprinter for about 5years , runs great only needed a service call one time easy fix, cost $120 bucks for a oil change ,ours is the 5cyc diesel, gets 20plus mpg ,don,t worry about service .in my part of the world ohio theres two within 50 miles. idle is no problem theres a switch where you could idle all night . ours a leisure travel van mod freedom serenity is our last MH ,we,ve had big A,s and bigger C,s but this one fits perfect. and if theres one big thing you gotta look at is the leg room. I,m 6ft 1 and can turn around in the seat any time.
