im working on that still as well, I can get junk skis all day long here, and I do mean junk, but none have trailers, trying to find a dual trailer with a junk ski cheap or else I guess I will have to pony up $500-$600 for one, As well I have three skis though so I may need to look at a 4 place trailer or make my own because they are all 2-3 seat skis.
Its really a pain, these darn seadoo trailers cost me as much as a boat trailer, heck I can even sometimes pick up a boat trailer cheaper.....crazy!
I am thinking of buying like a 22' foot or so flat bed trailer and removing the bed and converting to a 4 place trailer or 3 place I dont know, right now I have 3 but heck maybe I will add a 4th at some time. Why not, its nice to have a different ski to ride.....
