I agree with Norse, and from personal experience a Suburban would be my first choice in your situation. If you can find an older one that has been well cared for, all the better. The old '68 we had, with the 292 straight six was so simple I could sit on the fender with the hood up and my feet inside the engine compartment to work on it. The less bells and whistles, the less there is to break. That said, it would pay to learn a few basics of vehicle maintenance. You're not going to have to change the oil in the backwoods, but knowing that corrosion on a battery terminal, even if you can't see it, may prevent the starter from cranking and having the basic tools to fix it might save your life. A roll of Duck Wrap Fix silicone repair tape, about $5 a roll at Wal-Mart, can seal a split radiator hose or any other leaking item. A self tapping screw and piece of innertube can seal a small puncture in the oil pan or gas tank. I'm no mechanic, but all three of these things are from personal experience. And if you don't know how to change a flat, learn (a can of flat repair spray might work sometimes as well). One of those units that combine an emergency jump start battery, power inflator, work light, etc., wouldn't be amiss. One more from my history, know where your fuel filter is located, carry a spare and any special tool needed to change it. Any rig built in the last quarter century or so uses some type of fuel injection and the system is pressurized, so loosen the gas cap first. I replaced the fuel filter on a '97 Suburban in Glacier Park. And one more on fuel; all newer vehicles have the fuel pump in the gas tank and the fuel cools the pump, so don't run too low as it can shorten pump life.
