**UPDATE 11/14/2021**
Found issue to be wiring from truck battery back to camper. The wire gage (10) was not sufficient for the length of run. In my case the wire length is 20 feet. I have upgraded to 4 gage (bought 20ft jumper cables and cut off the alligator clips).
I had started another thread when I replaced the BlueSeas ACR with a Victron DC-DC Orion charger:

Hi guys,
I'm having an issue with my Blue Seas ACR (Smart charging isolator). Simple wiring, I've installed these in several trucks with dual battery systems.
My setup is a 2001 F350 V10 with 2001 FWC Hawk. Isolator is mounted in the camper. Positive cable from truck battery on one post, positive cable for camper on the other post. Grounded small wire to camper grounds which go to camper battery.
Camper battery (batteries) are two 6 month old Trojan T-105s in series.
Issue: when truck running (or with 200w solar) I can see the isolator not combining, even though both batteries are reading over 12.5V. I'd imagine if one battery was low (under 12V)it wouldn't combine. Right now I'm reading 12.4V on camper and 13.7V on truck and it's not combining. Anything I should look for?
About to throw it in the trash...
