The total load with both A/Cs running is 31 amps. I have never found the need to run both A/Cs when on the road; and since we do not dry camp when the temps are above 85 degrees, the 33 amps output of the KY is sufficient for our needs.

Interesting. Was that Onan KY 4000 and 50-Amp electrical service from factory? Or did you upgrade from 30A yourself?

MHSRV has one Hurricane 31C in stock where I can view the window sticker and it states an Onan 5500. A General RV dealer has another 31C unit and list specs as Onan 4000 and 50-Amp service. The Thor Hurricane Brochure (2 page pdf) states that 29M has dual roof air conditioner option with 50-Amp detachable power cord. Data is all over the place and needs revision for clarity. It appears Thor is combining Onan 4000 with 50-Amp service on some coaches.

Considering how many owners on this forum haul smaller portable generators to save fuel (like Honda 2000 or 2200) instead of running an Onan 5500, it makes sense an Onan 4000 may be a good choice much of the time. When only charging batteries or powering a single air conditioner, a 5500 is so oversized that it becomes inefficient in fuel consumption.
