How often will you be running the AC? If the answer is most of the time then get the bigger unit. If the answer is maybe once every 5 trips, or less, then get the 2 2000's.
I have a different brand but hooking up the 2 2000's takes time, one more thing to setup and take down every trip, and I dont need AC that often.
That being said, I bought a 3100 watt unit with remote start and love it! I was worried about the gas usage but not that big a deal. And you can run it on econ when you are not needing the AC. I also trip the 120v breaker for the fridge so it just stays on Propane.
