Having been away from RVs for almost 10 years, I'd forgotten that my biggest complaint about the two Tiffins gassers that I owned was how I almost froze driving them in New England in the winter. At that point in time, the DW refused to leave for warmer climes until after Christmas, so around the 28th or 29th of December, I'd find myself behind the wheel of an RV, wrapped in a blanket, running down I-95, with my fingers and toes imitating ice cubes.
The firewall on those motorhomes let the air in like they were made from cheesecloth. And now I'm wondering if my new to me Vegas is going to do the same thing? Any of you guys out there from northern states have any experience with this?
