As long as you will be working on solid, level ground, any of them have the ability power wise.
I used to maneuvered a 24' pontoon boat with a 122. My experience and sugestions are this:
First, if you will be using the stock drawbar with a ball installed, keep in mind that the ball will be quite low and close to the ground. Your trailer jack may not go low enough and you will need a different means of raising and lowering the tongue.
Second, backing up a long trailer with a short wheelbase tractor can get quite hectic because you are sitting so close to the pivot point. Plus you can't see what's happening on the sides such as you can see in truck mirrors when backing up.
The tractor you get, if this is it's main purpose, I would suggest fabbing up a front mount setup for the ball. I had a front ball setup on an old truck I had, and backing a trailer into anywhere with a vehicle going forward is unbelievably easy.
