Can Onan Microlite 2.8 handle a 13,500 BTU A/C?

I was thinking of upgrading my roof air from 11,000 to 13,500 BTU's. It's a Dometic Penguin. Can my Onan 2.8 handle it?
  • I thought I got a verdict here that a 2400is yamaha would run one.

  • My previous RV, an '02 class B Roadtrek C190V, had a 2.8 and an 11,000 A/C. The A/C was a house-type unit mounted inside the roof. I've run both the A/C and microwave at the same time, but the A/C was running (compressor on & cooling) when the microwave was turned on for 2 minutes. This was at about 3200 feet. The Onan labored audibly but took the load. IIRC, the Onan had about 275 hours on it at the time.

    A maybe-useful check would be to turn the current A/C & microwave on at the same time.
