i made my own. Spare 2x4s, spare plywood, spare can of black paint, and some spare hardware. I can remove it with ease, works like a charm. Don't have any good pictures of it but mine was free and works great (towed over 1000 miles this year with this setup and it works great) cut out slots for ski tips so the outside ski can hang over (trailer is 17'x8' plus 2' v)
