We're in a position financially, where whatever we choose, that will be it. It's a poor choice to do it at all, but a gals gotta do what a gals gotta do.
We're considering it a sunken cost, buy whatever, use it and enjoy it, and when we're too old/busted to keep going, sell it off and settle in at home.
As Sue said above, we are definitely leaning towards a TT, we know we'd prefer a MH, but since we own a paid for 2016 truck, the choice of a nice but much less expensive TT would be our best bet.
