I'll be interested in the responses. We have gone from a Montana to a Montana Big Sky and now we're contemplating going shorter. We have looked at Montana, High Country and Mountaineer. We really like the Montana 3610, but it is actually inches longer than our current Big Sky. I would add, though, that if I were fulltiming, I believe I would be looking at the Montana line, just because of some of the features such as temperature rating and the six point hydraulic level up system vs. electric. Good luck, and you've found a great source of information.
