My uncle drove my 67 up to NY from Columbia, SC, about 725 miles back in '96, I then convinced him to leave it up there with me
I then had the same uncle trailer it down for me in January '03 from NY to SC, 725 miles.
I have yet to do it yet, but I have taken my truck on 400+ mile round trips MANY times. Maybe someday I'll be taking another one home...
