Route suggestions Charleston, WV to Lancaster, OH

I'm towing a 46' DRV Houston (13'7" height) from Raleigh NC to the Jayco service center in Middlebury, IN next week. Google maps takes me via I-77 thru Charleston WV then via US-33 at Ravenswood. Then US-33 up to Lancaster OH where I'm overnighting at the Loves. The Good Sam's planner takes me up I-77 all the way to Parkersburg, then west across US-50 to get to US-33 at Athens, OH. That adds over 30 miles.

Has anyone traveled either of these routes? I don't see any showstoppers going the shorter way, but don't want to get caught in a corner towing this big rig.

Thanks!
