... will check in the morning although I don’t want to retire unless necessary.
What I say to myself during every commute ...NOT !

The guys will know better than I do, but it sounds like your fridge has a BIG draw and your battery does not have the capacity to provide that power to it. So...here is my question for you Solar Gurus.....what if the OP added a SECOND battery to his Alaskan? Would that be enough to offset the draw? Would he then be better off if he intends on adding the portable solar unit to have increased storage that the second battery would have?
Any info on how to wire up the second panel and the two controllers and two batteries to work in tandem would be interesting and perhaps helpful if the OP is running outta power....not enough power at night to run the fridge and interior lights, etc. after the sun goes down would seem to be a problem that a second battery AND a second solar panel might overcome.
Your thoughts gentlemen?

On another thought my Alaskan has two Gp.27 AGM batteries but fridge draws 4 amps. In the sun it barely keeps up if I want to keep batteries above 12 volts hence the additional moveable solar panel .the two panels together will keep me above 12 volts if the second cc is able to read the correct voltage. My concern is that the primary system may fool the secondary system into thinking there is more charge than there actually is at the battery. I have a trimetric but have not put the full system into full sun to see what kind of readings I get. The trimetric will read total input and output.
Turning fridge temps up helps but then I don’t get ice. Bourbon and water without ice just doesn’t cut it.

Getting harder and more complicated to have a simple drink on the rocks all the time.

2 way or 3 way fridge? 4 amps is only 48 watts. Seems like even with high sun angle loss that you should be able to keep up.
For me it's ice cream, but I hear you on the ice topic.
Where does that road go?

If I retire...Damn, there it is again....Rewire. I may try to tap into the factory plug where it connects to the truck battery and go thru the 30 amp cc. It should handle the load. Just more work to rewire.
