Tongue weight is typically 10 to 15 percent of the loaded weight of the trailer.
So if the trailer weighs 8,600#, 10 to 15 percent of that is 860-1290#.
So you take that TW 860-1290 and subtract it from your payload rating.
1,450 - 860 = 590
1,450 - 1,290 = 160
After you add a 8,600# camper to your bumper (with a tongue weight of 10 to 15%) you will have 160-590 # or payload left.
Remember you cant get to these figures by using dry weight numbers, you have to figure it from loaded weight. Also, you will have to account for people and other cargo, for example you have 160 - 590# left over for gear, pets, people, cargo, toys, WDH and bikes.
