Towing a fifth wheel back from anchorage ak February

People live in RV's in Anchorage every winter. It's much colder in upper BC/Yukon than Anchorage. Most are in RV parks and have a large propane tank delivered and placed under the 5th wheel overhang and have propane delivered for refills. And the drive....I prefer a winter trip, less traffic, no road construction, and the roads are smoother. RV parks may be closed but most northern motels have no problem providing power for travelers...income is income!
