What should backfeed there? All pins used for lighting have 0V when the truck is parked and everything is off. And the +12V line is not connected.
The computer not going to sleep for whatever reason might be a good theory. Incidentally, that would explain what happened with my own Silverado.
I'd still try to measure the base current with and without the camper plugged in.

Can it be anything with the 8 gauge ground wire that I have bolted to the truck chassis but I don't have the 8 gauge hot wire to the batteries? I was just figuring the ground needed to be hooked up in order to make the turn signals and brake lights to work.

The backfeed sounds plausible though don't know how that would work-being on light circuits wouldn't think they could trigger truck, even less how power could be trickling back on light wires of camper other than something looking for ground?

I would think that would mean that it shouldn't be able to drain the truck battery??

I'm reading/assuming that the trucks charge line is live.
Though didn't say whether or not its connected at truck engine bay fuse block, my understanding is the Chevy charge wire isn't connected from factory.
Its the only route that 12v can be drawn from truck hence my assumption charge wire is live. On the Chevy the charge line is always hot if connected. I would meter the receptacle camper is plugged into for constant 12v. Somewhere somehow, camper is connected to the trucks charge line.
AS trailer doesn't have a charge line (odd) and pigtail to camper, charge line isn't hooked up- yet camper is draining the truck battery. Seems you are NOT using truck to recharge trailer/camper while on the road, one option is to pull fuse on trucks charge line.

On the truck side of the camper plug, have you connected Pin #4 or not? It has +12V from the truck when you look at a plug diagram such as this:

Do you have a cheap multimeter? What is the voltage reading on Pin #4?

I tapped those into the 7 way at the rear of my truck.

I picked up a 2016 lance 865. It is killing the truck batteries when plugged into the truck. If it sits for a couple days without starting the truck then it is really slow to start.
On the plug I installed on the truck, I did NOT wire the 8 gauge 12v wire to the battery. I have the 8 gauge ground connected to the truck chassis. Then the rest of the wires in the plug are just turn signals, brake lights, running lights, and reverse lights. I tapped those into the 7 way at the rear of my truck.
Without the camper plugged in then the truck can go weeks or months without being started and it starts fine. With the camper plugged in, then it can only make it a couple days and it is slow to start the truck.
Any ideas? Also This still happens when the 120v is plugged into the camper to charge it.
