Welcome aboard the RoadTrip America Forums!

No, there are no roads on which you can legally drive where the SUV will offer any advantages. While the rental agency will be more than happy to rent you the more expensive SUV, and the gas stations will roll out the red carpet for such a thirsty beast, the fact is that the rental contract will specifically prohibit you from taking any car off "regularly maintained roads". Use your money wisely, get a comfortable sedan with all the creature comforts.
