Dometic 8501 3 way fridge performance. followup.

Further to my thread:136444, here are the results using the fridge on 12 volt. As I wasn't travelling, I connected a lead to the Anderson plug from a 12 volt battery using a Ctek 15 amp battery charger. the volts at the back of the fridge were 12.48.

Every thing the same as last 2 tests &outside temp was 29deg.
Startup...fridge.....23.8....freezer...22,2
after 1 hr .............16.2............... ..-7.5
next 1 hr...............11.6.................-13.3
next 1 hr.................5.6.................-13.5
Temp difference. 18.2..................35.7.

The 12 volt surprised me as to how well it performed.
On a follow up on the gas results, I checked the regulator & the gas pressure at the fridge was 12.6 in water column & not at the regulation 11in. I reset the regulator& gas has quietened down somewhat. I expect a better performance on gas now.
