Yeah, I don't like the idea of using steel either, but it's all I can do for now. Today, I'm ordering a winch post & bow stop from Trailex. They have an existing model for the SUT-200-S trailer, but it should work just fine on the trailer you & I have. That is, it'll fit the trailer, but may require some adjustments to fit the TI. Here's the link (it's the model shown at the very bottom of the page.)http://www.trailex.com/SUT-200-S.cfm
Originally, I was not going to buy this item, but then I thought about my wife possibly having to load the boat by herself in a remote location if I happen to be out of comission due to my bad back. For 50 bucks, I'll pay to keep her happy.
As for the handle, if you look closely at the top photo in my earlier post, you'll see I've bolted a tongue handle to the coupler. They're cheap... about 7 dollars or so at most marinas. I already love it, and I'm NOT going to use a tongue jack, 'cause lifting this thing with the handle is easy.
