Re: how to swap trailers on land
How many guys do you know that have the solid 2 1/2 ton cherry pickers (like mine).
FOUR of these, blocked into place, with a couple of straps, lift the boat, drag out the old trailer and roll the newer one under.
If the parking lot is pavement, a couple of 2 X 4's nail thru into the pavement should be enough to keep the pickers from rolling in.
