Check all battery and large electrical connections. I found many not tight, and also found hardly none of the cable connections tight. Manufacturers just don't take the time, just get it built.

I had the same problem and was very frustrated until I spoke to Lippert. The system needs VERY GOOD batteries at full charge. Having my unit in storage, picking it up and heading for a destination was not enough to get an adequate charge on two group 24 batteries.

I upgraded to three group 27 batteries and added one 195 solar panel. Problem solved. I have not had low voltage problems in three years now.

On another note, my battery storage is very tight, making it hard to check water levels. I am looking into a water maintenance system. system

Auto leveling - voltage drop

Follow your battery 12V leads back to a panel behind a basement wall where there are multiple connections. On my 2017 Jayco Pinnacle all 8 connections found there were not even hand tight. Securing those connections fixed my low voltage woes when leveling.

He said everything checked out, and it had something to do with the residential fridge (even though it happens when the cooling is turned off). It has two batteries, but he said adding more wouldn’t help, because it doesn’t raise the voltage.

I won’t auto level with the truck under the nose of course, but I have pulled my truck next to the trailer and used the cord.
