Ok, /out/, I'm considering going on a long camping trip this summer, and I want to have my own vehicle to do it in. I'm planning to go somewhere in West Canada, in those mountain ranges. I'm not terribly concerned with comfort, so what's a vehicle that has good gas mileage, carrying capacity, and can reasonably accommodate 3-4 people for up to 3 weeks, but would not be terribly cramped/small?
