Like some others said, pre-cool 1-2 days (depending on outside temps) on shore power if available or LPG. Ready to travel, make sure your propane burner is going on the fridge (usually can hear the little burner). Load all your food and drinks and your ready to travel.
Wife & I drove about 3K miles in Oct. had some pretty strong winds too. Just left fridge on auto and had no problems.
