RE: How to build a good spear shack?
Well how much do you want to spend and can you weld aluminum. I can shoot you a drawing of mine. I went 4'x5' makes it small enough to move easy yet roomy enough. Builtframeout of 2''x2''aluminum welded together, insulated with 2'' foam and sheeted with aluminum riveted on but welded all seams. On the inside I used thinplastic paneling and used the cheap spray on truck bed liner more durable then paint. I built it to last for ever it cost more but you never have to worry about it rotting or getting moldy.
