RV vs Domestic fridge

I am looking to replace the fridge in my '72 with a newer model and have been seeing different people using domestic propane/2 way fridges in their rv's. I have also read that the domestic ones will not hold up to all the vibrations and bumps they will get while towing. Any feed back?

How would you vent it? On electric it will still make heat, on propane heat and combustion fumes.

Huh, that must be a local thing. Generally when I see a non-RV fridge in an Airstream it's the cheapest thing Wal-Mart sells (Haier etc.) and it's an electric-only dorm fridge.

Some people actually beef up their batteries a bit and run the dorm fridges off batteries w/ an inverter when traveling and only stay where there's power, and they say it works for them.

Home 2-way propane fridges aren't all THAT much cheaper than RV fridges. A 6 cubic ft "Unique" brand propane fridge is about $1k, a 6-cu-ft Dometic RV fridge is about $1.2k

I’d likE your advice About turning off the DOMETIC three way (propane/12VDC/120VAC) fridge when in storage. We run it all the time, even when it sits in our driveway, unused. How long would it last on 120VAC? Is t a big deal to replace when it wears out?

The Eternal Fridge

My experience is that a Dometic 8 cu ft on 120VAC burns about $1+ of electricity per day.

The 2 way propane fridges, if properly leveled, can run on electricity until the heating elements burn out. Keep in mind that some experts say fridge fires often seem to be associated with operation on electricity.

Propane fridges run best when the propane burner is operating.

We ran a propane fridge all summer on electricity for convenience, but recently shut it down in order to lower the electricity bill at our rural estate.

I have met folks who say their family owns a cabin with a 70+ year old propane fridge. It only runs on propane.

We do not operate the Dometic fridge in our RV when in motion. We put the food into 12VDC fridge/freezers if it will be more than 8 hours until we can stop & get leveled again.

Please, no comments about how you run your fridge on the road all the time. Unless you have installed an ARP device, it is a bad idea.

When it wears out

I realized that I didn't address your question about when it wears out. If the fridge's electric heating elements burn out, they can be replaced.

How difficult the replacement will be is totally dependent on access to the area where the heating elements are located.
