The first pic is of my stock trailer for my 2004 TR 21X. The other three pics are of the new jack that I bought from BPS. It is the 1500 Big Wheel model. I wasn't trying to cut corners by not buying another Fulton. This one got great reviews and was half the price. I just don't see how to get a proper install out of this. Does anyone have a direction for me to go? I am thinking that I will be needing to take this one back and buying a Fulton just like the one that came off of it.
