Plug the holes in the roof, especially the AC and the single pane bathroom skylight if yours is like mine. The slide has a lot of air leaks around the bottom under the fridge and behind the dinette especially, plug these off. Put covers over the single pane windows. I know this makes it dark but it helps.
The single fan AF provides to blow air into the basement isn't sufficient for really cold weather because it's too far from the front of the basement. Add another fan to the step area up to the cab-over bed and one in the access cover to the plumbing under the shower. Put them on a switch controlled by you so you can use electric heat and still blow warm air to the basement. These two additional fans will blow enough air to keep the fresh tank and under the kitchen sink above freezing. You may want to consider disconnecting the outside shower and city water lines from the main trunk line as it passes under the kitchen. All that should get you comfortable to below 0F temps. I was able to use mine at -20 last year without freeze-ups.
You can get really crazy and add extra insulation to the basement walls and floor like I did but I'm not sure it's necessary. With my new NL all I've done is add a front basement fan and it's been good to -15 F so far this year with no frozen pipes. Keeping warm air going to the basement will help the floor will be warmer too. I was able to keep my basement within about 10 degrees of my inside temperature even at below 0 F temps on my 1150. It takes a bit of work to finish where the factory left off but the 1150 can be a great All Season camper.
