I'd heard that many small RV's were overweight empty. So, I was a little concerned when we bought our 2002 Minnie (24-1/2 feet) without first weighing it.
Fortunately, my concern was unjustified. With full gas (50 gal), full water (46 gal), my wife and I and two dogs, we tipped the scale at 10,460 pounds.
GVWR on the E350 is 11,500, leaving us 1000 pounds for "stuff".
So far, it handles much nicer on the highway and on forest service roads than our old Alpenlite/F350 truck camper combo.
It looks like the rear springs are sagging a bit but I probably wont mess with them.
