Cover windows. Use incandescent light bulbs that give off heat. Lap robes and head and shoulder covers. Good luck.
X2 on the windows. Glass is your enemy and the front windshield on a class A is a big looser of thermal energy. We have cut Reflectix ("bubble foil") insulation to fit in all the windows in our rig for especially cold weather (we have 3M crystalline film for hot weather). We have the Reflectix panels in right now since it's decided to sleet and snow in the upstate Carolinas - and down in the low 20s tomorrow night.
