Well all of the connections aren't good. The voltage at the gen should be within a half a volt or so of what it is at the battery.
Did you check the negative connections.....grounds ??
You have entirely too much voltage loss from the batteries to the generator.....indicating a bad connection somewhere. Outside chance that the solenoid is bad but not likely I think.
Note:
If you are not plugged in.....and the truck isn't running.....it should be trying to start from the house batteries only. plugging in adds the converter/charger. Running the truck should bridge in that battery too.
