info on 1997 Onan Marquis 6500 LP Generator

I have a 1997 Monaco Windsor motorhome that came with an Onan Marquis 6500 LP generator. It was plumbed into the LP tank via the "vapor" outlet. The book said to hook it to the "liquid" outlet. It wasn't running correctly so I took the coach to Camping World and after 4 weeks they said they had to change the connection to the tank, replace the regulator and some other gizmo connected to the regulator. Now it runs fine but stinks. I have used many LP machines and none of them run making that stink. What's up? Any ideas? I'd appreciate some help here. Feel free to contact me at atlasven@comcast.net.
Thank you in advance.

If you are now running the generator on the liquid side of the LP tank, what you are probably smelling is the mercapsan oil (odor-ant) that has accumulated at the bottom of the tank and in its concentration is not burning up completely. Once you run this excess out out of the system, it will probably start running without as much odor as now.

I'm also running the same generator. Are you able to use it to run both air conditioners?
