Keeping the fridge cold during travel without propane or generator

[Bohemian]

Generally speaking, it IS legal to drive with propane on.

There are specific restrictions. Propane and power must be off when fueling. Propane must be off when driving through most tunnels and other restricted areas. These will be marked and warning will be given, though sometimes it is easy to miss.

If you approach the Baltimore Harbor tunnel, you have about 5 seconds to pull off into the supplied area to turn off the propane once you see the sign. Impossible to make without knowing beforehand. There are also restrictions on how much propane you are carrying.

You could freeze a one gallon jug(or 1/2 gallon) of drinking water prior to your trip. Put in in the fridge just before traveling. Combined with the cold food in the refrigerator it should keep your food cold enough. Let it melt upon arrival and use for drinking water or re-freeze for the trip home.

Fridge on auto and propane on all the time. Furnace on if temperature is lower the 35F. Keeps the basement from freezing. We have never winterized this unit. Just drive south when temp to cold here in the north.
