I've always needed 4wd since I spend a lot of time camping in the backcountry and driving off-road or on jeep-only trails.

Here's my current ride, a Nissan Xterra:

It has a truck frame, not unibody construction, is small enough but, with the rooftop carrier, holds enough for extended trips away from civilization (a couple months at a time sometimes) plus 10 gallons of gasoline. All the camping gear (5 sleeping bags, two tents, etc.) goes in the rooftop carrier. Two cameras, two tripods, 50 filmholders, lenses, etc., etc. ride behind the driver's seat.

It's served me well since 2008.
