Not knowing the exact specs of your F150, I see it as being similar in many ways to my Trailblazer. You should have no trouble towing a 17z. I think you need a W/D hitch myself, but that depends on how stiff your springs are. When I had my '03 Kiwi 17a I needed because the Trailblazer's suspension is soft.
