Its all about timing. You can do the 95 boogie but need to time your self around the major cities. Up early stop mid afternoon and go again. When Towing we have taken 78 to 81 sb to 66 to 95. Brings us out near Fredericksburg where we bed down for the night. That's the hardest part of the trip. Wake up and head dwon 95. 77 takes you further west to make the cut over. As you pointed out the biggest issue is around the major cities. Last sb trip while towing we left Long Island 3 am and were in fbergs around 1:30. took a power nap went to dinner then shoved off the next morning after bfast and it was easy sailing.
Hope that helps
