I am with the group that just dry camps with electric and uses the wash house.
We do carry a water jug for cooking and night time potty trips.
Since they are usually weekend affairs, snowshoeing or hiking, we can get by with an electric heater and save the propane.
Salt on the roads is a problem but it does not keep us from driving our car. A spring wash and TT paint touch up is required after a few years anyway.
If you are a real winter bug, a four season TT might be a good choice but for a couple of trips a year, our 25 ft Dutchmen does just fine.
