From the way you talk, I don't think you would be very happy with a TC. As you know from past experience, they are great for traveling or towing, not great sitting for a while.
I think you would be happier with a 30-32' FW which you could pull with your current truck. Then when you get set up some place, you have the truck to run around in for sight seeing. Since you are retired and have the time to spend a week or two here and there, it wouldn't be like trying to drive around with it all time.
I plan on retiring in a few more years and we have already decided that for the first year or two, we will take two to four month long trips with the TC while we explore the country but not staying in a single place for more than a few days because we want to see "everything". After we have seen most "everything", we will be ready to start going back and really explore our favorites place. Then we will probably have a small 8' TC and pull a 30' TT giving us the best of both worlds.
The TT will be to give us our space during bad weather, room for extra gear, and used as a base camp. But we will have the TC for taking one or two nights out in the boonies where the TT won't be able to go. Also give us all the amenities while we are out exploring for the day.
