You do not want too light a tow vehicle for a 10,000 pound GVW Classic. That is a lot of mass and sail area for winds to much against. Consider a diesel engine for the exhaust brake action that saves wheel brakes from getting hot on steep mountain descents.
We converted our Classic to disc brakes and have a truck that weighs in at nearly the same weight as the trailer. We have no acceleration or stopping issues at just over 19,000 pounds going down the highway.
