I have a jet sled Jr that I was hauling my gear with which was not very organized. So I decided to build a wooden box to fit in the sled, to hold all of my gear in and to have the auger mount on top of the box. I saw something similar on this site. The box is a bit heavy but OK, but the problem is that I think it is too tall and narrow, it tips side to side. It looks like Smitty sleds are the way to go. I can make it wider and have the auger next to the box to help with the height issue. I like how many have made theirs on skies and want to do the same. It looks like 2x6 or 2x8 are used to mount to the skies. How is this done? Bolted or screwed? Is wider the way to go?
