Are you thinking of moving to Alaska to live full time with what is basically a 40' MH or just taking a trip to Alaska?
We have a 40' DP and brought it to Alaska for the first summer and then took it back stateside. We took it back, as planned, because we mainly wanted it for use during the winter someplace in the southwest. At one time I owned a TC for several years also.
When we brought it north and for the summer we had it here, it was fine. But while we were traveling in it I'd see all these places to stop - nice fishing places, scenic spots, a place to spend the night or something that would have been good places to stop if I'd had the TC, but there was no way I was going to get into with a 40' DP pulling a Jeep.
So if you want to come up for the summer, you'll do just fine. If you're going to move here, I recommend something smaller. At the moment I'm shopping for a used 24' - 26' TT to use here while we're home for the summer so I can get into more spots.
