I drove my '53 Henry J from Minneapolis to Auburn, Indiana and back in 2004. No problems but not the most pleasant ride I ever had. Seems I have been spoiled with modern cars and driving one that's 50+ years old takes a bit of effort and discomfort so I certainly applaud you as your journey was much longer than mine. I also drove my '52 Henry J Vagabond from Minneapolis to Missouri Valley, IA a couple of months later. That was only 360 miles (one way) so it it wasn't too bad. Auburn was 658 (one way) or something like that. Henry Js do just fine on long trips, I also drove one from Omaha, NE to Sterling, IL for a meet years ago and drove a '51 J from Minneapolis to Springfield, IL for the national back in '77. It can be done.
