I built 1 that goes up down about 5 yrs ago never really fine tuned but it worked well, I made a smitty out of aluminum tubing which my 1 man flip would fit into with skis for runners I then placed right angle aluminum on skis 4-5 inches long 4 places on skis that I drilled and placed bolt thru , to 12 inch legs 1 inch sq aluminum , this allowed legs to go up and down. I then made 4 5 inch right angle brackets on the aluminum frame that went around the tub of the hut and hooked up the same way. this allowed the hut to raise up and down with my help of course. as I cobble my thru want I had in my mind. I came up with 4 springs which hooked to upper frame , top of 2 legs to bottom of the othe other 2 legs. in essence just like coffee table deal. when I step on ends of skis and pick up a little the 4 springs help lift the loaded tub up with ease to a height of 10 inches over the ice. I drilled hole in the rear top of legs and use a quick pin to lock it to a vertical angle on back this keeps back from spreading when pulling the front I have a hole drilled in each front leg which allows for a bungee to be stretched and hooked with ease. this gives the whole setup stability. probably not enough to drag behing 4 wheeler but for pulling works fine.. when I get where im going I can let it down or just drag tub out of frame and fish. when I get back to truck I let set up down with my tub and contents in tub and pick up front place on tail gate the pick up back and slide in . just fits under cover. still a work in progress . but eventually will be fine tuned. the frame and skis gives me the length to place 1 end on tailgate and lift the other. if theres no snow then it gives me length to pull out of truck drop 1 end and pull hut out of frame and go, sliding frame back in till I come back. sounds like a cluster im sure but works well and saves back, until I get pic ,, hope it helps someone with some new ideas, I seen the original on here years ago woth just wood and pivot points. cant remember who it was but was and original idea from him , I cant take no credit . im not much for words and explain but hope people can make a little sense of what I said . goodluck stay safe
