Larry, you aren't looking at the real figures here. The gross weight of the RV is actually: Empty Weight 8,496 lbs. 1,699 lbs. 10,195 lbs. Gross weight. The pin weight of this loaded RV will be 2400 pounds. Let's assume your four passengers weigh 600 pounds, your hitch weighs 200 pounds, and 100 pounds of miscellaneous baloney. All of a sudden you're toting around 3,300 pounds in your F150. Can it be done? Sure. Should it be done? Not on your life nor on your family's lives.
You are far, far from having a proper vehicle. Just jump to a 350/3500 and relax.
