We do the lightbulb thing around here too... I found these THERMO CUBEs from AMAZON that really work great. These have different models for different turn-on temperatures.

My OFF-ROAD POPUP trailer sits outside here at the house so I use the 35 DEGREE models which turns on at 35 degrees and then turns off when the temp gets up to 45 degrees...
Also for my OFF-ROAD POPUP setup I run into alot of quick setups in the winter in very low temps alot. I found that things inside my popup would freeze up pretty easy behind the cabinet areas. My trailer does not have remote heat strips anywhere... What I did to solve this problem was to install these small 3-inch round vents (LOWES) inside all of the interconnecting cabinets that literally wraps around the inside of my POPUP trailer from the front tent bed area all the way around to the entrance door on the front side. The small round vents are just glued in place. These small vents allows air flow all the way around the closed cabinet areas. Next to the door area I mounted a thermostat controlled DC axial fan panel that will pull air all the way through the closed cabinets.

This worked out great for these cold nights getting warm air inside all of the cabinet/storage areas... ADDED NOTE: I got this idea from Don a few years back... PIANOTUNA
