My goal is to run 100% on propane like I have in previous trailers. I simply light it off a day before we leave and shut it down a day after we return. Simple, we can wet or dry camp. I manually shut down the propane for ferry rides and if I feel there is a safety hazard.
People seem to feel 120 vac works a little better then propane on the 6.7 so I know I can manually plug in the 120 vac if I have it and AES will find it.
At this time I do not have solar and I don't want my tow vehicle or trailer battery being discharged trying to power the refrig.
The way I understand it the AES system tries to search for 12VDC, then 120VAC and last .. propane.
I found a number of people who feel that the AES is switching this way and that (more below) which results in uneven temperatures in the unit. Because so many folks have trouble, but it seems to me from various causes, I choose to run on propane only for a while to disable the variables of the AES system.
AES searches in that order under the assumption that there is a solar charging system capable of running the refrigerator on 12vdc.
It also 'automatically' senses the voltage on the 12V line and will disable propane for 15 minutes when it thinks the tow vehicle has shut the engine down. The purpose is to make sure the propane is shut down if you are at a gasoline filling station.
I started by 'picking' gas when I started the refrig. But after reading all the posts about the refrig not working as well driving etc. and trying to understand how it switches off on voltage changes ..... I decided to fool the AES into thinking all it has is propane.
For me the AES is a variable I don't fully understand. All my other frigs we manual so I wanted to be comparing apples to apples as close as I can.
Hope that helps, Mel
