"Bobsyouruncle" just over-wintered in Alberta in his EEE, he plans to get an Arctic Fox for the next winter
Another poster here (who's handle I now forget) has done two in North Dakota in an Arctic Fox.
Both needed Propane fills every few days. The North Dakota (Oil-Patch) skirted his, plus ran heat-tape, plus put thermo heaters under the rig, plus, plus...
Both had problems with their refer. No RV refer made is designed to work properly with the exterior coils at a temperature colder then the inside of the refer. You actually have to HEAT the area around the outside refer coils to keep the refer from freezing up.
