I wonder if you are leaving home with a completely full charge? I agree with
the majority who say the voltage does not get all the way to the trailer battery high enough to give a good charge. I've demonstrated this myself.
Example- we boon docked in cold weather and left the CG with pretty low
trailer batteries. Drove 2 hours home. At home it was nearly dark so we
turned on lights in the trailer while we unloaded a few things. Lights went dim in just a few minutes demonstrating I had gotten pretty much zero charge while driving home.
BUT- I keep my trailer at home and keep a battery tender attached.
When we leave it's with a FULL charge. Typically when we arrive at a CG
and plug in my converter might surge for 5 minutes or so but then it's back
to maintenance charge.
If yours is running full bore for hours I gotta wonder if you left home with
a full charge.
