We have family in MI near Toledo and travel from/to NC frequently pulling our FW. Traffic flow on I77 is usually good. It can get congested at Wytheville, VA at the junction of I-81N(I77S)/I-77S (especially northbound). We've traveled Ohio Turnpike to I77 and we've traveled I75S to O-15E/US23 to US30E to US250 to I77. You'll have 3 tolls (2.50 truck/trailer)in WV. Traffic slowdowns due to accidents is anybody's guess. We prefer to non-turnpike route due to very low traffic and nice countryside.
