Inverter vs Generator
For years I carried 3500 watt generator and found its use going down as I travel nationally and use parks most every night. It was those long haul days I would need it for the microwave or a/c to slee...

The fuse in the charge line (truck sending power to the trailer) is somewhere between 20 and 40 amps, the voltage drop from the trucks fuse box to the trailer batteries limits you to as well. There is a 0% chance you can run the trailers AC off the trucks charge line, not counting the trucks alternator puts out far less then 150-200 amps at idle that is needed by the inverter.
If you are going to plug the trailers power inlet into an inverter powered off the trailers batteries you will want to disable the onboard converter while you are doing it.
You may get 10-15 minutes off a single battery running the AC, but without putting it in a lot faster then 20-30 amps, the truck will only give you another minute or so of runtime. Then the trailers battery will be dead - no lights, no water pump, no propane detector, no fridge, etc.
