Well...that's because of a number of shortcomings of the MBS based motorhomes.
The first is that the Sprinter has a GVWR of 11,300 lbs...and most of the motorhomes come off the assembly line weighing 10,000 lbs or more. So all of them are right up against that limit immediately.
The second is that, in their wisdom, Mercedes has been unwilling to produce a modified Sprinter chassis with more rear axle width. So motorhomes, which can be a little top heavy, strain against a relatively narrow base.
And a third is that, again in their wisdom, Mercedes delivers their chassis with suspension components which, as near as I can tell, assume that the vehicle will almost never bump up against the GVWR. Their springs, shocks, and anti-roll bars all tend to be just barely sufficient and much better performance is obtained when some, or all, of those components are upgraded.
I suppose we can't lay all the blame on Mercedes - the motorhome builders have to take some responsibility for shipping products which are right up against the GVWR even though they're aware of the problems. FR, at least, went to the extent of upgrading the rear anti-roll bar (are they still doing that?) which certainly helped.
Ah well. Other than that, it's a very user-friendly chassis!
