I use this with the spare tire in the low position to get my boat and trailer off my own concrete boat ramp. that works great! I have a winch that lowers the whole structure into the water and then I throw the boat off the trailer. I had to make a brake for this so I could put the boat back on the trailer but it was pretty easy. It's also great for storing a spare tire, wheel bearing and ready for on-the-go use in an emergency. The metal is painted, not galvanized, my only complaint.
