I bought a 2019 F350 SRW thinking I could tow any 5vr out there I decided to purchase. I acquired a 2021 Solitude 377mbs. I ran across the CAT scales and found out I'm within GCWR, GAWR, but 400lb over on GVWR. Sad day for me. I'm going to rearrange my cargo to the rear of the trailer but doubtful I can get under the GVWR.
I have an F350 4X4, SRW, diesel and because I bought the long bed, 12,400 lb rated truck I have a CARGO weight rating of 4120 lbs. But that has nothing to do with the gross veh. wt rating of the trailer if I'm understanding what you're talking about. Are you over the GVWR on the truck or the trailer? If you're overwt on the GVWR of the trailer, ie, your trailer is rated for a max wt of 16,800 lbs and it comes in with an unloaded dry wt off the factory floor of 13,200 lbs, you've only got 3600 lbs of payload on the trailer. BBQs, tanks, generators, food, clothing and all of the gear we live with in our rigs adds up real fast. Rearranging everything in the trailer isnt going to change the total wt of the trailer. But that rating has nothing to with the truck and it has everything to do with having too much stuff loaded in it at any given time. I pull a 376TH with mine real close to 20,000 lbs, complete with a full size touring Harley in the rear and have pulled that rig over 15 percent grades with no issues whatsoever.
