A few years back, I made a trip of a little under 3000 miles on the TW. I was in Germany at that time and decided to do a tour around the country. The off-road parts of the trips were great, but the high ways not so much, especially the unlimited speed ones. I would not recommend choosing a TW for very long trips. On my way back, I had to stop at a train station, check
timetables and service centers at the station, and take the train back. It was too much for me at that point.
