It was earlier this year, but I made one huge improvement in the Tiger's cold weather livability. It has the Suburban noise-blaster 'direct discharge' 16k Btu furnace (no duct work, hot air & return right thru the front plate). It sounds almost like a jet engine, and uses a lot of battery power. The thermostat was on the wall pretty much right above it, at the rear of the kitchen.
I like to sleep with it pretty cold, but hate to get up in the cold. I finally got around to extending the thermostat wiring, and relocating the thermostat. Now it's right beside the head of the cabover bunk, where I can reach it just by sticking my arm out of the covers. No midnight blast of noise, no weak house batteries in the AM.
I also made a three-sided baffle that fits around the front of the furnace for the night. It's a temporary trial rig, made of rigid fiberglass insulation & aluminum duct tape If I decide to go with the idea, I'll rebuild it with some kind of hinged wood casing.
Wrong time of the year to post this, but maybe it'll give someone with a similar issue some time to get inspired and do something.
