I picked up my new Raptor toy hauler in early March, just before the country went nuts. I had ordered so there were several things that changed my UVW. I got body paint, dual pane windows, deleted the patio system, queen bed (mattress swapped on pickup with the one from the motorhome trade in), and added slide awnings before taking possession. The UVW on the side sticker was actually a bit less than the web site published UVW but my adds, awnings, 2 batteries, propane) changed that anyway. My tow vehicle at the time was a 2017 Ram 3500 SRW LB CC Laramie diesel and I had an auxiliary fuel transfer tank in the bed, 51g. I weighed at the local CAT scales on the way home, full fuel all the way around, and was very close to my RAWR, VERY close.
I figured that loading the garage would cause a significant weight shift off the pin. Garage had HD motorcycle and my tools/extra stuff with an estimated weight of 1200-1400#. In August I took a trip and loaded for camping, weighed at a CAT scales along the way and I was over my 7000# RAWR, just under my tire weight ratings, and right at my payload (based on sticker in door jamb 4207#). Again full fuels and only 30+-g fresh water and empty waste tanks. Full fridge though. That is just me on the trip, no significant other, pets, kids, etc in the truck.
Bottom line for me based on actual weights at a CAT scales I was at the ragged edge of weights with the SRW. My garage loading had much less pin weight shift than I was expecting, maybe 20% change. Had I filled the fresh water tank, heavily loaded the basement storage area, put less weight in the garage, I would have been significantly overloaded on both truck RAWR, payload, tire weight ratings, etc. FWIW it towed "just fine" very stable and strong, BUT I didn't want to be at that ragged edge especially with little water on board. In November I traded the SRW for a 2020 Ram DRW with the HO and AISIN. Only a couple of short trips so far and still need to hit the scales but with the payload margin, I'll be good. But I will go to the CAT scales in March on my next trip.
If you haven't actually weighed, I suggest doing so. Published weights are a fantasy of the manufacturer.
