need some reviews on a 'generac ix2000'

I have a 5500-8500 Generac 11 hp Briggs that I bought new in oct '01. Can't help you on the noise level as this is a working gen set. Never had it camping nor would I want to hear it or camp near it.
Its been on top of LEQ horse trailers/flatdeck trailers/hanging under a front loader on straps in all kinds of weather and abuse running 24/7 even going down the road o n extended runs. I have no idea how many hours it has but its got to be a bunch.
It still starts the first pull. Can't get any better service that its given us.
