Our coach has a QD10K and personally i think its too much....An 8k would do us just fine.
I always expected the 8k fuel consumption to be less (until i really started looking at these numbers, posted below).

1/2 load consumption of the 8k & 10k are close to the same, but the 8k does consume more ( .49 & .43 gph respectively)
the 8k sucks a bit more fuel than the 10k at full load (1.02 & 1.0 gph respectively)....almost a quart more per hour.

the 8kw weighs quite a bit less than the 10kw (420 lbs vs 765 lbs)
the 8k has a variable throttle, the 10k throttle is constant (which might account for the 3db increase in noise).

most toter's only have one AC unit - you would be fine w/ an 6k (with plenty of wattage to spare).
I'd look at the service intervals between the units too - things like oil/fuel filter change intervals & coolant flush intervals.



the above specs came from onan - they also list other (propane & gasoline gen specs here) - http://www.cumminsonan.com/www/html/.../rv/F-1123.pdf

man a little bit of research tonight is making me feel slightly better about my 10kw....
knowing i never run it at full load - I'm probably consuming less fuel than it seems, and the oil change interval less frequent (@ 250 hrs).

of course the oil capacity is less in the 8k vs the 10k (2.8 qt vs 5.9 qt)
coolant capacity is 4qt vs 6.6 qt - so over all the 10k is gonna cost slightly more to service.

I've got an 8k Quiet Diesel Onan and it seems to be plenty of power for my two roof airs and everything else.

First off, its NOT a QD 7500. Like I posted it's a RV 7.5 and it IS a 50amp.
So please refrain from critiquing some ones post without having all the facts.
Thank you,
Patrick

oh so its MY fault you didn't provide any DETAILS ?? even now ??
perhaps knowing the model number, hours etc would help a buyer....

is that a single leg of 120 at 50a ? or 2 legs of 120 at 50a ? details details details

you might notice nearly ALL 7.5 (standard diesel) units are 30A...so how would one know !?!?
