Battery charging in Cargo trailer
I camp out of a small cargo trailer. Currently have it set up on solar with 2 6 volt batteries. Long story short I am looking for someone with experience charging batteries off tow vehicle that is not...

Well, if he has a 7 pin connector, he'll have a live feed he can use. If he has a 4 pin, he won't.
First question is; how much power are you hoping to get from the vehicle?
Usually, the wire on a 7 pin connector is 10 gauge, max, maybe only 12 gauge. Given the length, and how thin that wire is, I would expect it to be a significant limitation on how much power you can move.
If I wanted to move a lot of power, I'd be using something like 4 gauge conductors, run from the vehicle battery back to the rear bumper, terminating in a pair of Anderson connectors. Similar connectors on the trailer. I'd get a set of jumper cables and mod them to have Andersons on each end.
No need for any device, just unplug the wire to separate the batteries when you are camping.
Oh, and you have to fuse the hot wire on BOTH ends, near each battery.
