Snowman9000: I don't think so. I say this because I have never thought geez, it's drafty in here. Now, someone else might say so, but I can't based on our experience to date. We have been parked in torrential downpours in Florida and did not feel any drafts. Our coldest night so far has been 26 degrees, and we only used a $20 portable electrical heater from Walmart to keep warm. Warmest day so far has been 130 degrees in Las Vegas. Very few rigs can offer the view out of the back like our mid-bath, and we appreciate that quality especially in scenic areas like Alaska.
