Have 378xl pulling ford explorer. Thats my direct route south out of WV and north on return. You should have no problems. Top your tank off in Wythville VA before getting into WV and you will save a few bucks. There is a flying J with RV lane I always use. The fuel tax in WV is higher than VA and if you are towing have $3.25 ready at each of the three toll booths on I77 from Princeton north up thru Charleston WV. You will give that V10 a good workout pulling up to Beckley from Princeton.
