We had the same concerns and more about pulling our 36ft TT to Alaska.
After much thought and research as to what others did, we brought a 2002 Lance TC. Made the trip (3 mths and 12000 miles) and sold the TC for $500 more than I paid for it. My gas millage was twice what it is pulling the TT. Saved a LOT of money!!
We stayed at Wal-Marts 90% of the time and pull offs 5% and parks 5%. Saved A LOT more money.It was just the two of us - my wife(75) and me(71).
Go for it !!!!!!
It was the adventure of a life time !!!!!!
PS: Being retired military, you can handle anything!!!
