Ours is TC is mostly packed. The propane and diesel fuel tank in the truck are usually topped off. Our power was out for 24+ hours last weekend so we drove the truck out of the shop and used solar and battery power to keep some perishables cold that wouldn't fit in the downstairs freezer. Temps outside were in the 30s and 40s so not cold enough plus we live near bobcat and bear country and the raccoons and other critters hang out.
Because we live near a working forest, there can be fires so we could always use the TC as our escape vehicle.
