We find that tolerance for time behind the wheel gets shorter as we get older.
When we were younger, 1000 miles per day was normal and 1500 miles was doable (one driving, one sleeping 24, hours a day driving).
We did a 1100 miles from Richland, Wa to LA, Ca in one day when we bought our TM about 2 years ago. It was far from fun or vacation like and it was 24 hours, non-stop (except meals and potty stops).
Last weekend, we drove 350 to visit our kids. It was a 6 hour drive (without the TM) and we were done-in when we arrived. We determined then, that 6 hours was the max that we would want to tow the TM in any one day (keeping in mind tear down and set-up at the end of the drive). The # of miles traveled will depend largely on terrain and speed limits.
Were are in our mid 60's now. We are planning on towing our TM to Alaska in 2013. I'm wondering if that 6 hours will still hold when we get closer to 70
