Driving through Mountains

Just wondering--considering driving a medium sized moving truck with car tow from the Midwest. Does anyone know if this will be difficult once we get into the higher elevations?

Most of the roads are fairly wide, and as long as you stay below the speed limit (probably somewhere in the 65mph range) you shouldn't have any issues controlling the vehicle.

However, depending on the truck's capabilities (engine, horsepower, all that good stuff), climbing hills might be difficult. To avoid overheating, and to make sure there are no problems getting up the hills, you may want to turn your air-conditioner off while you're climbing.
