Well, never thought I'd see this thread get revived, but heres how I solved my delimma. I purchased one of those black plastic toolboxes you see in the back of pickup trucks. It's fairly wide and would go from one side of the truck to the other. I then installed racks into it, and a blower and vent holes. I used a fan from an old air conditioning system that was taken out of my old home before I moved.
I simply put my gear inside, and turn the blower on, and within a few hours, it's as dry as the day it came out of the store. Might not be too effective in freezing temps, but its small enogh to fit in a garage, and if heated, still effective.
