Looking to sell my trailer in the off season as well as do some wet sanding on the hull so I'm in the market for the carts/wheeled stands that can support a boat properly yet be moved around a shop.

Are these available commercially or custom made???? If available please forward info or a link. thanks!

Like these?

Yes they are avail in a few different styles. How big is the boat that you are looking to put on there?

29' Phantom pleasure. basically a stretched magnum bottom

Those in the craigslist ad are basically what I'm looking for. Is it normally just one up front and one at the transom?
