Thanks Mark; I guess I don't know...I have the A/C manual in my hand, but it's written for 3 models, capacity's of 7,180, 11,000 and 13,500 like you mention. I'll go out and look on the actual unit...maybe there's something on it that gives it's exact model #.
and...good news for me:) it's the middle size, so 11,000 like yours. Sounds like the nudge I need to buy the little Honda finally! They have the 2000i Honda generators for 850 at the local place, the cheapest I've seen them.
My A/C unit wasn't factory, but they had it installed new in 92, still have the slip for it. The former owners were great about keeping every manual, etc...
wait a sec...I just saw you said you use it while driving?? um...where is it running?
