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 i...

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.
The backfeed would require a problem with the wiring harness in the camper. Somehow a stray voltage getting applied to one of the lamp leads feeding back into the truck from the camper's battery. A long shot probably not worth pursuing.
Another place to measure current would be the ground lead of the plug. If current is returning to the truck through there then that's a sure sign that the 12v is getting there somehow. Only problem there is the 8ga line bolted to the chassis is an alternative ground path. Maybe check current on the ground leg with and without that 8ga wire connected?
