Agreed, but you are going to go through a lot of propane. If near civilization, it's not an issue. If you are camping 60 miles from the nearest fill up, it might be.
For what it's worth:
We so far have only camped where it is "cold" at night - not in situations where it remains cold throughout the day. I have no desire to camp for days on end in constant temperatures below freezing - or constant temperatures in even the 30's. I'll leave that up to the hunters.
How much propane one might go through of course depends upon many factors. One of the most important ones other than how low the outside temperature goes - is how big is the volume you must keep warm?
We chose a relatively small Class C (24 feet) for, among other considerations, ease of maintaining it's interior comfort in all kinds of weather when drycamping. The sleeping, bathroom, and cab areas of it can be blocked off with built-in curtains that it came stock with. In freezing daytime temperatures, we'd of course keep only the kitchen, dinnette, and lounge chair total area heated to conserve propane and still be comfortable at an interior temperature of, say, 68-70 degrees. At night we block off only the cab area, but set the propane furnace control at 58-63 degrees to maintain a nice level of "get up in the middle of the night" comfort.
Our RV came with a winterization package which includes 12 volt heated grey and black tanks and a built-in battery storage compartment large enough for dual 6 volt or 12 volt deep cycle batteries. The fresh water tank is kept warm by propane furnace outlet tubes that pass right by it in the same cabinet. The RV's propane tank is also 18 gallons, which is not bad for a small RV. I estimate that we should be able to get by drycamping for 3-4 days in 24/7 freezing temperatures on our propane tank capacity.
Of course another main problem with winter camping is keeping the batteries charged up. This is no small challenge to do when the sun cannot be counted on to do it if one has solar ... which we don't. We have three ways to charge our dual Group 31 deep cycle batteries when drycamping - the main engine's alternator, the built-in generator fueled from the main 55 gallon gas tank, and a small Honda generator with spare gas for it that we carry along for backup. Of course whenever the main engine alternator is used for battery charging the RV can at the same time be heated by the cab heater, and whenever the built-in generator is used for battery charging the RV can at the same time be heated with a couple of 1500 watt electric heaters - thus saving some propane using either charging choice.
It never hurts to be ready for a large variety of camping situations in case they should arise, which we tried to keep in mind when we bought our rig.
