I will be using the rear 12V source for my Dometic fridge on a trip while driving. While stationary it will be on a 12V Lifepo 20ah battery and solar. The fuse is 20A and the unit specs out that full draw is 7 amps, although normal running amps are 1.25. I think I am ok but was wondering does anyone else do it this way? Or use any other accessory on that power that draws the same or more power without issue? Have a great weekend peeps.
