Search for a better trailer jack wheel
After hurting myself struggling with the factory jack wheel on the AmeriTrail (cheap jack wheel installed WAY off center, too high from the ground and on a trailer with too much tongue weight) I picked up a Fulton F2 jack wheel for a lot of money ($150). It is very expensive but it's the only one I've seen that offers the adjustability of the starting height before engaging the jack: the mounting plate is bolted in a sliding track and not welded to the outer tube so when you install the jack you can adjust the relative position of the mount and the outer tube. By setting the starting height of the jack wheel just off the ground I don't have to jack the wheel down very far which means the wheel swivels properly under that ridiculous tongue weight of 500lbs. (When I try to make the current factory wheel swivel, the wheel just slides sideways leaving black skid marks and digging chips dug out of the concrete driveway). Curious if anyone else has experience on the reliabilility of this F2 jack wheel as so far I'm very impressed with the engineering design of it and the trailer pivots like it's on an air hockey table!
