We're going heater-shopping this weekend in Missoula, so by Monday we should be staying warmer in our rig. Thanks so much for all the suggestions and for sharing your personal experiences with various types of units. I think, because of our 2 Australian shepherds and 1 long-haired cat, we'll stay away from the propane heaters. I'm not crazy about using space heaters in the first place, and thinking about those animals wandering around a heater makes me nervous. Whatever we get, we'll have a chance to try it out in the hotel before we leave town--at least that way we can hear what, if any, noise the heater makes and see how much warmth it puts out on a low setting. Of course, the warmth test won't be very scientific, since the hotel room will be warm anyway.
If only we had a 50-amp site . . .
