Cannot run A/C while at highway speeds
This is long and I am sorry for that. But describing the setup and problem is necessary. Here is my situation. First of all, this is a 2005 Hitchhiker II 32.5 UKTG fifth wheel. I have built a ge...

OP: your test #1 doesn't really prove anything, and you said it yourself. running the generators with no load is running the generators with no load.
They do not run "wide open" with no load, even if the eco switch is off, they run at a higher fixed rpm. the throttle and engine load is still low. As you add electrical load, the throttle opens more as engine load increases because the generator is harder to turn.
if there's a shortage of air (oxygen) due to a vacuum, it's not likely to affect the generators at idle, with the throttle mostly closed they don't need much air.
