That door molding is pretty rugged, although I suppose it could break. I do have some high density polymer I could have used but the strips are only 3" wide. If the molding breaks I'll use those and double them side by side. Oh yea it will be squirrly on that trailer, realistically it is only going down the road a few miles, top speed probably be 15-20 mph. Drag the shack itself on the lake for a half mile max.
I like the idea of attaching the skis individually with angle iron and lags. Once I get the skis out though, I'm probably gonna bring them home. I'd hate to have to build another sled to transport them.
