We store our RV in our yard so we can start the fridge 24 hours ahead of time on electric. We'll then start loading the fridge the night before departure. The longest we haul is a little over 4 hours and I do this with the fridge turned off - everything remains very cold in the fridge and no thawing of frozen items. We are in the Northeast so this may not work in the Southern states. One tip: we freeze all meats in FoodSaver bags. Amazing how much more food you can get in the freezer when there's no air in the bags.
