In my case I just don't get alot of charge at the trailer batteries coming from the TRUCK Alternator when driving. I only plan for my truck alternator system to give me TOP OFF DC CHARGING back to where my TRAILER BATTERIES are installed. Also your INVERTER will want to pull alot of current from the TRAILER Batteries even just running the fridge.
I suspect you are going to need more batteries on the trailer side if you will be running the INVERTER alot.
Using a multimeter across the battery terminals should show 12.6-7VDC when the batteries are fully charged. If the truck motor is running or you are connected to SHORE POWER the multimeter should read 13.6VDC or more (Up to 14.4VDC in my case) depending what charge mode it is doing at the time.
Just my observations here...
