I got my answers this morning from the Crossroads sales rep for my area, Kevin Combs. Note that the answers below are my understanding and not direct quotes, so any inaccuracy is probably due to my own ignorance.

- What level of insulation is in the Elevation line (R values), specifically the TF3310? Is the garage equally insulated as the rest of the coach?

Sidewalls are R9 (Cruiser is R15), Floor is R15 (Cruiser is R28), Roof is R15 (Cruiser is R27). Yes, the garage is equally insulated.

- Does it have the Polartec (zero degree tested) upgrade, which is standard on all Cruiser Sahara & Cruiser Patriot/Provincial models?
|
No, because it's totally different construction. The Elevation has laminate walls with block foam insulation, and the studs are aluminum, but not 16" on center.

- Are the Dual Pane windows an option, and are any of them in the wild with this option yet?
|
Yes, they're an option. They would result in a bit more of a delay when ordering new.
No, it's not specifically heated (no air blown in, no tank wraps).
I was definitely surprised by the answers, since I was expecting the construction to be the same as the Cruiser line. I was wondering how they kept these things so light, though (TANSTAAFL). I'm not sure this is a dealbreaker for me. They are basically using the same constructions as the rest of the industry (AFAIK), and they are still backing this with the 2+5 warranty.
My biggest concern is currently the prospect of freezing water lines/tanks/pipes (no experience here). If we stay out in it a little too late in the fall season, or take it out of storage for a January trip to Florida, what can we expect? Do we have to "winterize" the moment the temperature drops below 32 in the first scenario, and do we wait to de-winterize until we get to Florida in the second scenario?
