Customer Question
Can I run my...

Can I run my Dometic RM 7401 RV fridge on two deep cycle 6v 232amp batteries-in-series for a 7 hr. ferry ride when propane has to be off?

Mechanic's Assistant: I'll do all I can to help. How long have you been dealing with this?

I'm getting ready for a trip which includes a 7 hr. ferry ride. Normally we run the fridge on 12v while driving, propane while dry camping, and 110volt in campgrounds.

Mechanic's Assistant: Do you plan on doing the work yourself?

There is no work involved, just a setting of the controls.

Mechanic's Assistant: Anything else we should know to help you best?

That's all.

I don't think they will last that long. 12 VDC use pulls quite a few amps. If you had some solar back up that would help.
