Motorhomes on Mercedes Chassis

Currently in a 2016 Navion built on a sprinter chassis. No toad. Bought used with 24k miles, now have 48k miles. no problems with the drive train. get approx 15mpg at 60-65, lower in the mountains. The one thing to be mindful of when purchasing this vehicle, new or used, is that Winnebago neglected to correct front end camber, so tires wear out unevenly. Have it checked! previous owner learned the hard way, and i have heard this story from numerous other Mercedes/Navion owners. Otherwise, it's a great vehicle. We drive it in cities (LA, Denver, Sacramento) in the desert, mountains, on good and bad roads.
