Generator

I would set the fan to low, which will help.  Someone else will need to step in with instructions for the digital thermostat.  1000 feet shouldn't make a noticable difference.  Not until you get up several thousand feet.  The rule of thumb is you lose 3.5% per 1000 feet, plus 1% for every 10 F above 60 F.  So go to 3000 feet at 90 F and you've lost 13.5%.

A year ago last fall we met a gentleman out in South Dakota. He had his 3k inverter Honda mounted in an aluminum tool box in his pickup. He had it all vented out and locked up. Very quiet and very secure. Nice set up if you have a pickup.

The Supco Hard Start Capacitor is headed back. Instead of helping, it killed performance. Without, the generator would surge as the load kicked in, but settle down and run. I installed the hard start capacitor and it immediately put the generator in overload, which cuts the current feed (I guess, to protect the generator's inverter from being damaged). I removed it, and the generator can run the AC again.

I had hoped this would be an inexpensive way to make the AC work easier with the generator. I was mistaken. I guess I would have to go with Dometic's Smart Start system, but I don't want to spend over $400 to do so.

I have a 2012 RPod and the spec for my air conditioner are AC & fan start is 23 amps and run 16 amps

I was careful to wire it in parallel with the capacitor like I read. I was really disappointed when it caused the generator to overload instead helping the AC to start easier. I also figured that something must have been wrong with it. That's why it went back. Since the generator will start and run the AC, I will wait and see if I need to do anything. Hopefully, I won't need to.
