I have found that a smallish hydraulic jack placed under the chassis tube behind the seats and centered will do the trick nicely. I use a 3/4" thick pine board for the cushion. The clearance is very small so that a very low profile jack must be used. I had thought about sliding a 2X4" but that reduces the size of the jacks even more and I have yet to find one.
Putting a dolly under it is a good idea. I like it. That way I could re garage my regular car in the winter! Must take measurements!
