I've thought about it quite a bit. Have seen some decent ones go at the forest service auctions for reasonable prices.
Fuel is one thing, but the reality of driving them is another. 55mph, hot, and noisy. At least with the deuce I've driven.
I'd rather do like osme people, get a 24ft box van with something like a DT466, and have a camper front half/hauler back half.
