Bob, I checked into that as well; same problem. When the truck batteries are full charge, the alternator goes to float. The alternator does not read the trailer batteries, and if it did and started charging, the truck batteries would be overcharged. I checked on a second voltage regulator for a second alternator but no one that I spoke with could/would address the issue. I’m old school and still have a 1985 E150 with alternator and separate voltage regulator. I’m still planning.
