To clarify my earlier post:
The OP asked about the "perfect" cold weather rig. We have had three aluminum framed RV's: a Four Wheel Camper, an Alpenlite Camper, and a Dutch Star diesel pusher.
Yes, there are engineering trade offs between wood and aluminum frames. Personally, I was so convinced of the superiority of aluminum, that our first three RV's were aluminum. I never even considered wood.
I only bought our current wood framed camper because it came up on Craigslist and I got too good of a deal to pass up.
My PERSONAL experience and personal opinion, having owned both wood and aluminum , is that a wood makes for a superior cold weather rig. Yes, there are issues with wood. But, for cold weather, wood's better.
