How do you know these are your weights? Did you weigh it or is this the mfg's figures or just your best guess? Typically, the tongue weight of any type of tt (htt) is around 12 to 15 percent of the actual weight of the trailer. Even at 5100 lbs, the tongue weight will be over 600 lbs.
I will go weigh it Saturday, I have a truck stop not too far away, a Pilot. Do they have the scales I need? So do I weigh the suv on the scale w/ the trailer attached to get the loaded weight, then remove the trailer and weigh just the suv by itself and then finally the suv and trailer together? So three weights? I had estimated 500lbs of stuff since its just bed linens, a cooler of food and some drinks and food in the fridge, 3 bikes, 3 chairs and a grill and small generator. Thanks for all the info, I appreciate it.
