I'm in the same boat. I have a 2007 Toyota Tundra with the 5.7 liter engine in it and I haul a 2 horse Sundowner goose-neck and I so feel like I don't have enough truck. I don't go over the weight limit and it got electric brakes, but I won't haul more than 2 hours with it. Unfortunately I owe so much on the truck it will be a while before I can upgrade to an F250 that I should have bought in the first place. You live and learn...
