I have driven my '51 Suburban many times throughout the mountains of Tennessee, Virginia and North Carolina. Just watch your gears and don't depend too much on your brakes. I never had any problems getting up the hill, but then I never went much over 6000 ft. (Mt. Mitchell)
For many years this was my only vehicle, so I thought nothing of taking a 1000 mile vacation trip. The glory days were when the speed limit was 55. Interstate travel is now a little more problematic, but not out of the question.
