with a gasser, you should hot have any problems.. Sure you won't run up and down hills at or above the speedlimits, but we have driven all over eastern tennessee and further north with no problems. Just don't push it too hard, and let it shift down and do its thing. We have gone across from west to east and back several times, I-24, I-40, and a lot other small roads, with no difficulty. But if the road changes from pavement to gravel or dirt, start looking for a place to turn around. Those hills are a lot harder to back down than drive up.
