There is one nice thing about a propane fridge. An older one that needs a manual light will work and keep stuff cold regardless of the state of the batteries or electrical system. Newer ones are tied in, so if the batteries die, they do.
What I've wondered is why Dometic or another maker doesn't make a fuel cell that uses propane, and have that (as well as a small battery) as part of a refrigerator, perhaps with the ability to charge the house batteries. That way, even if the house batteries are dead, the fridge will still run and have electricity to keep going.
