I have a 2011 Cyclone 3950. What is the 12 v amperage requirement to run the refrigerator (in gas mode)?

The users manual for Dometic refridgerators list using a 3 amp fuse for the 12V controls so this would be gas mode.

5 amp fuse for 120V heater
and if you have the 3 way 12-volt heater, a 30 Amp fuse for the 12-V heater.

Page 13 of the manuals.

Understood that there is a 3 amp fuse. But what is the draw on the battery? I should have clarified... I want to figure out how much battery I need in order to support the fridge for say, a week. I dry camp 90% of the time.

I believe it's an RM2682 domestic

I found a parts service manual for a similar model to your Dometic RM2682. The link below is a manual for the RM2652.
It lists the AC 120V power for the heater is 2.7amps
The control board that uses .5 amps at 12 V.

I found additional parts list that also describes the control board for the DM2682 as using 0.5 Amps at 12V also.

Thank you very much for your help! I decided to go with an additional 12v deep cycle vs building a bank of 6 volts.
