Battery Isolator - Parasitic Current
Does the typical battery isolator subject the vehicle battery to any parasitic current when they're in the "cut-out" mode (secondary battery disconnected)?

Our truck now sits a while between TC trips so I use a small charger clamped to the truck battery and plugged into the stick-house. The "2a" charger sits at 13.4v forever; it is not like a trickle charger that shuts off.
I can't float the house batts in the TC on the truck and float the truck battery from there anymore via 7-pin like before (Chev has no isolator like a Ford does) now that I have the Renogy DC-DC in the camper, which does isolate the truck from the TC.
The Ford Class C engine batt is floated the same way with a small charger on it while the house is on converter float.
Some have a little solar set they use on the engine batt for that job.
