If you are going to use the tow vehicle as a "generator", use jumper cables and not the 7 pin.

A 1500watt inverter is pretty large, a smaller one would be better. The danger/issue with a 1500watt inverter on a single or even dual batteries @ 12v is it has the ability to pull a butt load of amps, more then a 12v lead acid system can sustain for any length of time. A 150watt inverter would run the loads you are asking about.

	We are new to the travel trailer world and have a 2016 182. We mostly plan on going to camp sites with electric, but hope to do some boondocking next spring. I understand the basics of propane and the difference between AC- DC. I understand that it would take a larger generator to run the AC than we care to buy at this point in our journey. But I do have some questions about the battery and charge. If we put the fridge on propane, and everything else on battery, we will basically just have lights and the Jensen radio pulling power I think. If I leave the car hooked up to our 7 pin and running for a couple hours here or there, would that be sufficient to keep the battery charged? I also have a 12 volt battery jumper/air compressor that I use on the boat or car when the battery gets low. If I hook this up to the Rv battery( not while the car is hooked up) , will it act as a second battery? Sort of like having two batteries? And my final question is about using a 1500 watt inverter. It is meant to be hooked to the car while running and has three 110 plugs to run small things like tv or computers. I originally bought it as a back up in case our power went out during a hurricane. A poor mans generator, I guess. Can I hook this inverter to the Rv battery while the Rv is hooked up to the 7 pin and getting some sort of charge? Or does it need to be hooked up directly to the car battery? Thanks for any help in understanding how these systems interact.
