Inverter did your rv come with this??
I'm wondering if you have one do you get a lot of use from it? Will a dealer install it and at what cost? Can you shut off your dash board air and run your ac off it? Do most units come with it instal...

My Monaco gas coach came with a 3000 watt inverter and I can easily run the microwave and my entertainment items at the same time. The way the coach is wired, the AC is not wired to be used by the inverter circuits.
To the OP, here is the math. A 15,000 BTU AC unit uses approximately 1,500 watts of power when running. It uses a little more when it starts the compressor. 1,500 watt 120 volt draw from your inverter means that you are sucking 125+ AMPS from your 12 volt system. This does not take in to consideration the efficiency loss with the inverter. That means that you would probably need an engine alternator to put out well in excess of 125 AMPS, just to break even, which sort of means running the AC when the engine is idling is probably not going to happen. They certainly have automotive alternators that are capable of that output. Mine is 140 AMPS but an alternator is not a free spinning assembly. As the amount of draw goes up, the amount of drag increases on the vehicle engine and this will lower your already poor fuel mileage. Not to mention the heat generated by a continuous alternator output of 125+ AMPS.
Not saying it can't be done, but it doesn't make much sense to do it.
