Only caution to building a skid shack is that you still need to get it to the lake (loading, hauling, and unloading) on a trailer. I built a 6 X 8 five years ago and love the shack, but it's a pain to transport.
Initially started as a lightweight 6x8 on a square aluminum frame, added 10ft 4X6 skids, comfortable height with a shed roof, steel roof, then 3/8 plywood exterior painted. 1 1/2 x 1 1/2 (ripped 2x4s) frame with 1 1/2 rigid pink foam insulation. With a battery, heater, and 20lb tank on board it comes in right at 1400 lbs. So it can add up in a hurry! I've hauled it on a snowmobile trailer (sketchy, and less than 10miles at 25mph) but now have a 16ft utility with a drop gate, winch it on, and the wheeler still fits side ways on the trailer in front of it.
When I do it again I'll just try to find a 6X10 V nose aluminum cargo trailer and build out the inside. Wheeler can still pull it out with a dolly or ski kit for the tongue, and when you're back to the landing just hook it up to the truck and drive the wheeler in the back of the trailer. Cheaper than a Ice Castle by a long ways and you end up with a real cargo trailer that handles the road way better.
