There are some excellent vehicles that span the gap between a 12mpg 'cruiser and a 50mpg Jetta, that will get you and your family out and enjoying this country.
The way I see it, you'd be trading a vehicle that is poorly suited for what you want to do due to size/ground clearance, etc, for
another vehicle that is poorly suited, due to extreme fuel thirst and the propensity to luring you into spending more time slapping on accessories than actually driving it overland...(If this is what you REALLY want to do, be honest, accept it and realize that you'll simply enjoy driving a classy 4x4 wagon around town and on short camping trips.
Nothing wrong with that
To me, the middle ground is something like a
subaru forester(25mpgs or more),
Diesel jeep(20-22ish mpgs), diesel or subaru powered
westfalia (AWD, or RWD, about 20-25mpgs), or maybe a nice example of a
trooper, Cherokee or
Montero (all of which get around 17-19 mpgs while travelling, usually)
None of these is a cruiser, but then again, ALL of them will take you further on a $4.00 gallon of gas, in comfort and style, than the cruiser will, and honestly, if actually getting out is the goal, is a point that might be worth your consideration.
