Long time lurker, one time poster, thought I'd share some recent weight tickets that have expedited my HDT project. Trailer is a Grand Design 3170BH, truck is an '06 GMC 3500 Dually (with a Transfer Flow 50 gallon tank in the bed). Just a little background that this truck doubles as my hunting / fishing truck (with a topper) so fifth wheel really wasn't a consideration as I need the space in the topper for my extra curricular activities.
Truck weighed all on CAT scales...
10,320 (5020 front axle and 5300 rear axle) - truck in "fishing/camping" configuration with 84 gallons of fuel, 2 adults, 2 kids, Finn the dog, and camping stuffs
18,800 (4640 front axle, 6720 rear axle, and 7440 trailer) - weight distribution hitch, 84 gallons of fuel, 2 adults, 2 kids, Finn the dog, camping stuffs, and empty RV tanks
19,480 (4440 front axle, 6920 rear axle, and 8120 trailer) - standard hitch, 84 gallons of fuel, 2 adults, 2 kids, Finn the dog, camping stuffs, and 1/2 full gray, black, and freshwater tanks (give or take)
So the auxiliary tank weighs 263 pounds and full has ~350 pounds of fuel in it, for a total of ~500 pounds. We just got back from a month long Alaska trip and I can say with confidence I wouldn't do it without having extra fuel capacity. Having said that, even if we didn't have the tank we'd still only be 500 pounds lighter. In current form and loading we're a whopping 40 pounds under max GVWR (11,400).
My conclusions are as follows (and somewhat obvious):
1. An HDT based hauler is in the works
2. A shocking number of people towing big bumper-pulls and 5rs in trucks similar to mine (similar GVWR) are massively overweight (the only "luxury" items we carry are the extra tank, some tools, and a grill)
My only question to the group, though, is would you expect more than 200 pounds difference by using the weight distribution hitch vs not?
