Thanks for the post Dutchmensport. Good suggestion for someone liky yourself who does not live in your rig full time like us.
Not going to be wanting to get up at 2am and light the stove. A vetless propane heater with thermastat is what Im looking for.
Don't have to worry to much about oxygen depletion or carbon monoxide poisoning, these rigs with all the slides and such are not very air tight. Plus the heaters are highly regulated. Will still crack a window or two open though. Thanks for the post.
