I pride myself on being able to back a trailer with ease. Be it a small utility trailer, car hauler, 40' gooseneck machine trailer, boat trailer, or a large enclosed trailer. But, the "hardest" trailer(s) I ever backed was my 5er. I never could figure out WHY I had so much trouble making it go where I wanted it to go. It dawned on me one day that the axles were actually farther forward than "normal". It didn't really make it any easier, but more manageable........I guess.
