 ==== workaround: heavier wiring ====
-It's also possible to run a separate and heavier cable from the TV to the trailer;  this would minimize voltage sag.  If a plain isolator is used with heavier wiring the voltage will still be insufficient to fully charge lead batteries.
+It's also possible to run a separate and (much) heavier & more expensive cable/connector from the TV to the trailer;  this would minimize voltage sag.
-Heavier cabling + a DC-DC charger could provide correct voltage to the trailer battery.

-This setup would be:  starter battery -> isolator -> inverter -> 120vac devices
+This setup would be:  starter battery -> combiner((A $25-$40 VSR (often marketed as a smart battery isolator) might be easiest. Could go even cheaper with a regular relay but you'd have to hunt for a D+/IGN signal.))
