I prefer the space-saving side-by-side configuration, so cogged belt and two pulleys suitable for 30hp cd service - or, rubber-isolated coupling directly to the provided-for area on the flywheel - or the nose of the engine, which is spline-shafted for PTO service - 1725rpm is right in the Diesel's max torque max efficiency band - run there all year at max fuel economy - and, that copper-wired Chinese generator is like a swiss watch, nothing like that clunky aluminum-wired stuff you've seen on a Briggs or Onan (got several of those non-running, 2000-3500watts)
I know what you mean about the problematic Generac / Onan stuff, to say nothing about the replacement costs. I've got one of those that cost me 3 grand, and the powerhead only lasted 1000 hours before the head overheated and melted the brush housing. A simple enough repair... Except that Generac / Guardian / GeneracPower / Whoever they sold it to next decided to not sell simple parts anymore. You can ONLY buy the entire unit, IF you are lucky enough to find someone that still has them.
Why hasn't Honda developed a decent 5-7 kw genset for the RV market yet?
As for the engine speed / noise / fuel use concerns... I tend to believe that a gas version has to maintain the same fuel consumption almost all the time at the higher speed b/c of the stoichiometric requirements. My gas generator in my RV seems to burn 1 gallon per hour whether I'm hitting it with BOTH 13,500 BTU air conditioners, or if it's almost unloaded. The noise level almost never changes too.
I will say that I don't know for sure on the diesels, but my own experience with diesel cars says that the idle fuel consumption (or low-load) drops WAY down compared to the loaded usage. Lean ratios will do that.
