Fastest permanent fish house I've ever been in was a friends old 76 chevy pickup. He had removable floorboards with home made wind blockers that fit right in the slots. Drilled the holes, drove over them, and fished. If we got skunked, off we went. What a BEAST that truck was. I think he got about 3 gallons to the mile with that thing. He even had propane heaters set up in the back so you could shut the truck off. Good Gravy did we catch fish outta that thing.
