I have one of the "blackcat" coleman
heaters - works great. Can run at night as long as follow safety
guidelines. Doesn't have to be vented and keeps smaller gooseneck trailer with
dressing room,( insulated ), comfortable. ( about 24 sq.ft. floor space ).
One propane cylinder will last about 5 hrs or 6 hrs, even set on
high.
Also, as said, old style coleman lanterns good for
taking chill off too.
And, if have neither, sleep in hat and extra socks,
gloves; and either sleep in ride clothes, or place them in sleeping bag wiith
you. ( Makes me remember time went to sleep at ride, in back of truck with
camper shell, was pouring rain, and awoke to three inches snow, brrrrrrrr.
