Thanks for you response! I guess we may need to buy/use an inverter as well by the sound of it iat least during the summertime weather! Ps-your trial setup sounds very interesting!

As NRALIFR has said.
The 12v in 3-ways was designed to be used only when driving, and to "maintain" temps. And, over the years, many were poorly installed, and killed many batteries.They should be hooked up so the element only works when the vehicle is running, and now, they use modules that shut it off if voltage gets too low, usually about 13 volts. I added 12v to mine, RM2501, because I like to experiment,and I used one of the relay modules that they use in the UK and Australia, set the voltage to turn off the element at 12v. It can keep the fridge at 35f, but I have only used it 2 times, I expect it will not when it is 90-100f out. I have a small inverter, in case I have to take a long driving trip,and will use it on 120, especially in hotter weather,while driving.

We ended up swapping back and forth during the summer from 12v to propane to keep the food cold and as importantly, to save on the use of propane a bit.

(Plus propane has increased substantially here in the northeast so definitely want to use the 12v from the dc dc charger and solar as much as we can! Also, we don’t like running on propane as it’s not safe, legal or recommended.

Our fridge and hot water tank are never turned off (fridge on AC at the house). Goes months on a bottle, so never really thought about the price.

I've installed a couple of them, and can't find anything in the instructions that suggest not traveling with them functioning, which is why I asked. The legal part; each state is different I guess. Interesting.


'16 F550 CC, 4x4 with Link Ultraride air suspension, '18 AF 1150. Just so we can play with our snowmobiles, dirt bikes and fishing boat. And new 20' tag along...kayaks, bikes, mc's and extra water and food!!

For me personally, I'll 'precool' the fridge by having the camper plugged into shore power and using the AC option 1-2 days before leaving on a trip.

Then I'll transfer precooled items from my house fridge/freezer to the campers fridge/freezer. I'll usually SHUT OFF the campers fridge/freezer before pulling out of my driveway.

While I live in Oregon and travel mostly in Oregon/Washington and the temperatures generally don't get higher than the 90's, I've found that the campers fridge/freezer will keep my items just fine (no matter what time of the year it is) during the 1-4 hours it takes to reach where I'm going.

When I reach my destination and start setting up, the campers fridge/freezer will get turned back on set to AC (if available) and propane if AC is not available. I see/find no need for the 'DC' mode/setting at all.

Obviously YMMV,

Generally my first stop is a station for fuel. Back in the days when I had a gas powered truck I might make multiple fuel stops along the way.

While IDK about the laws where you live/travel around here its illegal to have a open flame while fueling. Besides, the stupid automatic 3-way fridges can often switch to DC and unless you have cut or otherwise disabled that element you might arrive with a drained or dead battery (it has happened to me before).

A better question might be: why do you leave yours on?

Well I guess saying illegal was a bit exaggerated.. but it is prohibited when at gas stations, in tunnels, and such scenarios - plus, it’s just crazy for us to use it as we already paid for other options (dcdc charger and solar chargers) … hence now we only travel with it on propane as a last resort - and as little as possible… primarily because of the safety factor of driving around on the roadways with an open flame burning propane which will cost us twice to burn/waste additional money when we have to buy a new propane canister or have it refilled.

So I apologize for mis-speaking as to it being illegal, but it’s definitely less safe to do in various scenarios. [emoticon]

Yes, but I was asking if it might resolve a temp issue for a 3 way fridge as well![emoticon]

Thanks again for the info that was provided!

Life is good! Life is too short to waste fretting!

I learn so much from the forum!!!

Thanks again!
