I agree. Not having any heat in the rig for 10-12 hours in this "neck of the woods" would play havoc on the plumbing in the "basement" unless the trailer were winterized.
However, for short trips, we travel without heat. My wife usually climbs in the trailer and turns on the thermostat while I register at the campground office, by the time she finishes walking the dog, we pull into the site and get unhitched, the trailer is warm enough for her to start setting up the inside while I level and connect the utilities. By the time I'm finished and inside, she's got something warm ready and the trailer is almost always warm enough to take off coats and gloves and get the weekend started
