Lol, yeah food floating in water isn't the best way to go. I've had fridge/freezers on-board all my four wheel drives, for years, and couldn't go without it. Even around town, going shopping is so easy and I can multi-task more through not having to head home with the cold stuff.

I'll switch to lithium on my vehicle and the camper trailer next time I need batteries but yep, the cost of them is pretty high right now.
