I don't plan on excessive use of the inverter, but would like to know if the vehicle battery would be protected from a deep discharge in case of heavier draw, like from prolonged furnace use, etc. (not likey in June, but I am in Michigan) .
Well, I am not sure what you mean about being plugged into the tow vehicle or what size inverter you are talking about.
There was a recent thread (I will try to find it) where the poster wanted to use an inverter to do what you want to do, but use the tow vehicle to provide power while it is running.
Many tow vehicles will not provide power to the Bargman plug with the engine off; but some will. If you have one that will, the draw on the truck battery will kill it much quicker than the camper battery due to the design of the truck starting battery.
Most starting batteries do not even post their "amp hour" numbers since they are designed to give up their charge in minutes (for starting cold engines); not hours.
