It will use a lot more gas than a standalone generator or inverter. It will also put a lot of unnecessary wear and tear on your truck and you run the risk of overheating engine or a dead battery.

The downsides you list here are what I'm worried about - except for the fuel consumption.

We used a 750watt inverter for over a decade with no issues, but obviously that isn't close to what we are planning on going to so the game is going to be changed a lot with a 5000watt inverter.

It is so clean and easy to top the truck gas tank off just before getting to the stadium - nothing to have to refill and spill - no gas jug, no heavy generator to have to move or worry about cranking. And it really doesn't burn much fuel. Besides, there is going to be some point where somebody needs to sit in the car and run the AC during the day at most games so it is likely to be running a part of the day anyway.

What I'm worried about is the drain on the Alternator.
I'm thinking of adding a second battery under the hood and hooking it up in parallel - Think that might help?
