Here are some figures
I went through a weigh station a couple of weeks ago with a 2001 H240, which should be in the ballpark for you:3,620 lb. trailer axle weight370 lb. tongue weight (measured at home)This was with most of the 4-days worth of supplies in the truck.The tongue weight is the right percentage and I have no problems with sway using a standard ball and receiver.The 98-pound outboard engine, boom, bimini, tools and electronics were in the boat, and a spare tire was mounted on the trailer.There was no water or gasoline on the boat.This is a pretty heavy load, given that the magic-tilt trailer has a 3,420 lb. G.V.W.R.My truck had 3,100 lb. on the front tires, and 3,740 on the rear tires. This, plus the 3,620 lb. on the trailer brings the load up to 10,460 lb.My truck's GCWR (fully loaded vehicle + trailer) is 14,000 lb., and is rated to tow up to 7,300 lb., so I have a good margin there.My truck's GAWR (gross axle weight rating) is 3,800 lb. front and 4,000 lb. rear, so I have a fair margin there.Hope this helps while you shop for a truck.
