It was a fun adventure with our one year old Unity IB. No tow car was needed since we only stayed for 1 or 2 nights in each place. We did our sightseeing in between destinations.
While in Kutztown, Pa we got lost and found ourselves at an old covered bridge. We were happy to be able to fit under it and continue on our way. Had we been traveling in our former A class, we would not have fit.
