Should I upgrade to 2000w in parallel or single 3100w ?

I just "upgraded" from my old motorhome to a Jayco Jay Flight. Unfortunately it has the 15k A/C upgrade which immediately trips the breaker on my 2000w Champion inverter.

With the motorhome I could run the 13.5k A/C, but this bigger one looks like it will be impossible even with a hard start capacitor installed based on the inrush and continuous current numbers.

My first instinct is to sell the 2000 watt and buy this:

It is slightly cheaper to just buy another refurb 2000W and the parallel kit, but it seems like a lot more effort to lug 2 generators. Is there a hidden bonus to 2 generators I'm not seeing?
  • After owning a 2000 watt Champion and now a 3100 Champion... I'll stick with the 3100 watt with easy remote start.

    2000w is much more portable...

    3 000 is way quieter
  • My brand new 3100 Champion will run my 15k actually at 4600 feet elevation. It will not run it at 7000 ft. If you are going to be above mile high get 2- 2k's.
  • To update this old post since I forgot (sorry!) I ended up calling supergen products and getting the dual fuel 2800 model since it's the smallest I can run my 15k A/C on. It works great!

    I can even use the regulated BBQ grill output on the back bumper to run it off the trailer's supply. However I found out that just using a straight propane hose has it's problems, the Champion regulator that came with it has 2 stages, a low and high. In order to run it off the trailer I have to adjust the gas flow with the valve after starting and loading it down. So I believe the ultimate solution is the take apart the regulator and remove the high-pressure part and just use the low one. There was a YouTube video of someone else doing the exact same thing however he didn't name it very well and now I can't find it! But here's the one I shot with using a straight hose:
