Last winter i make a folding sled(4 by 3 folded to be sure it enter in the back of my car) that become the 6 by 8 plywood floor of my shelter!(To be sure to not battle with it when to mutch windy) All the shelter is fixed inside the differents moovable part of the sled! Did'nt have time this year to try-it,, maybe in couple of week
