If you are in the market for a tough off road vehicle for zombie apocalypse survival (or whatever...maybe you commute in south side Chicago rush hour traffic?), people are going to tell you that you need a 4X4...but those folks are dead wrong. It just isn't enough wheels on the ground. Maybe 6X6? Gettin' closer, but that still isn't enough. What you need is this 1975 Lockheed Dragon Wagon 8X8 offered for $14,250 in Hayward, CA via craigslist. Tip from Kaibeezy.
This is about as heavy duty as you can get with a vehicle that can still travel on the road and I'd be really tempted to remove the rear 4-wheels and run this thing as the worlds shortest wheelbase truck, but I'm not sure if the front wheels turn separate from the rear -- handling could get dicey.
