The lighter trailer is probably over your tow capacity and the bigger one defintetly is.
the way they figure tow rating is a lot of smoke and mirrors.
10,500 assumes ONLY a 150lb driver in the truck and no options (aka light truck). they take the GCWR (total rated load of the truck and trailer rolling down the road) and deduct the weight of the base truck and the number left is the tow rating.
So your F150 maybe GCWR of 15,000 (my silverado is 14,400). Your truck IRL may way 5500lbs (my 4x4 4 door sliverado is a real 5700lbs!). So teh difference is 9500 lbs.
Still sounds good, huh?
Well, now you add the family to the truck..600lbs? And tounge weight (1000 lbs or so on that 7800 lb trailer) and now the truck has 1600lbs on it, plus the 50lb hitch and maybe bikes, firewood, cap, etc. If it's really weights 5500 and has a GVWR of 7200 you're at your limit on the truck.
take that 15,000 and deduct the 7200 your truck now weights and you're left with 7800lbs of trailer.
the 7800lb trailer..is that loaded max weight or 'spec' weight - which doesn't include propane, battery, food, dishes, chairs, bedding, etc?
