If you create a percentage for the dry pin weight divided by the dry weight of the trailer and then apply the percentage to the GVWR of the trailer, you will be close to the loaded pin weight.
Here are our numbers. Dry pin 2435, Dry weight 13050 = 18.66 percent
18.66 percent times the 16 GVWR = 2985 loaded pin weight.
This is why we choose the BH3575el to tow with our SRW 2015 RAM 3500 4x4 SB truck.
If this trailer was pin heavy from the factory at say 2900, then loaded pin weight would be around 3556 pounds and I would have been over my RGAWR. Chris
