I had no water in the tanks at all, but did have 2 cases of bottled water, and of course some beer, but not much else except DW and 80# pooch. Oh well, time to start stripping weight.

Forest River has the GVW rating set up with a 60PSI those Continentals are rated 2470 Lb dual configuration at 80 PSI. The Sumo's are rated 3,000 LB and everyone who owns the BM Sprinter based motor home will go over GVW and the stock jounce bumpers will never touch the axle. The bottom leaf of the rear spring released over 2" from the leaf springs above it and the tires still didn't come off the ground. Although there is only a six bolt configuration on the rear axle it should handle a load that would bottom out the jounce bumpers. The manufacturers would never have put an "E" rated tire on the vehicle if the axle would not handle that class of tire.
Sumo offers larger capacity jounce bumpers as well as additional bolt on helper springs for the Sprinter 3500. They do tell you not to go over the GVW because of manufacturers liability issues, but they would not offer these accessories if they did not thoroughly test to see that loading them to the capacity they rate them at would not harm the Axle itself.
Has anyone heard of a weightmaster in any of the lower 48 pulling a fellow motor home owner over and making them pass over the scales?
Bottom line is let your conscious be your guide.
Mine says I will do my best not to go over the GVW rating any more than necessary. I will not haul a trailer that weighs more than the 4500 pound/450 pound tongue weight rated trailer hitch. but I will be damned if I am going to do without especially since Forest river could have ordered MB Sprinter Chassis with beefed up the springs, and Mercedes Benz could have put an axle designed for 8 bolt wheels. They did put tires on it that are capable of almost 10,000 pounds
