I just did this recently. I put two older pwc's in my toyhauler for a week at Park Moabi on the Colorado river. I didn't want to break the bank on this. So what I did was make some stands out of 2" pvc piping. That I placed in the trailer. The Pwc's weighed 400 and 500 pounds each. The stands worked great to transport them in the trailer. The only problem is relying on four other people to help get them in then out of the trailer to the beach. If I should do this again I may pick up some Pwc movable stands off Craigslist. Then put some bigger wheels on them. Then do some kind of winch to get them in the toyhauler. Then at the boat ramp I could just slowly winch them out.
