If you're using the stock charge wiring, the wires are most likely too small to ever get a full charge (too much voltage drop). You could measure the voltage at the camper batteries to be sure -- should be over 14v minimum.
X3!!
I regularly see charge current over 50A @ 14.7V (and occasionioally/briefly over 100A)

Yes this is the size connector to use when you want to get that power from the truck to the trailer. Make sure that you are also using a high quality relay, so that you do not drain the truck battery when using the furnace at night while still plugged into the truck.
Grainger part # 6C 017 has silver allow contacts, and is rated at 100,000 on and off starts with 100 amps going through it! That should last the life of the truck and another dozen more!
It will also improve the ground wire - so your brakes might work better too. You might also want to upgrade the braking wire from the battery to controller to #10 wire and also controller to trailer connection to #10 wire. IT is designed to carry up to 12 amps for 4 brakes or 18 amps with 6 brakes, yet most trucks have a #14 wire to carry all that amperage, with voltage loss can lead to only 9 amps going to the brakes on a dual axle set up. THis was a recent post today about brake improvement!
