Seriously, an Astro is a better choice than a Caravan for a guy. RWD based, powerful engine for its size, engine takes many SBC mods, and built like a truck.
Makes me wonder what other than wood could be put in there. I could probably scrounge enough scrap wood on a weekly basis for my commute to work already though.
Quite simply, the Chevrolet Astro van. They are a good base no matter what direction you choose. On road? RWD based, SBC fits, 700R4/4L60E takes a beating. Off road? The AWDs love it and are easily lifted, 4" lift clears 31" tires. Hauling? More interior room than a Suburban. Towing? Up to 5000 lbs stock. Camping? Full size mattress fits in the back with plenty of room for gear. Kids? Seats up to eight while still retaining space for groceries. Snow? The AWD system seems made for it.
