I would indeed be interested too! I am about to put my Onan up for sale for the same reason. I don't tolerate
the exhaust in the rear bedroom and don't really like running the fan all the time it's on. Loud + the exhaust is just a deal breaker for me.
Someone suggested closing the window above it. Yeah, it really wasn't the window. Even my little portable generator gives off exhaust.
So, please - PLEASE share whatever you learn here. :)
thanks in advance,

On my 73 CanyonLands, the generator battery compartment access panel is in the living space and not sealed at all, and that battery compartment is open to the generator compartment, so fumes can come through there. I figured if I ever got close to using the CanyonLands, I would need to put some weatherstripping on that access panel.

Why not eliminate the dedicated battery, use the house battery, and
seal the access panel?

JWID,

Ken H.
I have a full size battery back there that I can use for a spare house battery and dry camp longer without having to fire up the generator (dual voltage fridge, no propane). The down side is that I have to be careful not to run both down too far or they are dead for good.

I can't add a battery up front for more house battery capacity. The members of my family are not petite. Because of the GVWR specs, I can have another battery up front, OR a family member in the passenger seat, but not both.

Both of mine are 73s, so the a-arms are potentially under-reinforced to begin with.

Barb,

I don't know if what I'm going to mention will help you or not but I'll tell you what that I learned from a fellow GMC owner. He carries a long PVC pipe under his coach. As I recall, it has an elbow on the end that fits over the generator exhaust pipe. When in use, the pipe is secured to his coach and extends a few feet above the roof. Exhaust fumes and sounds are released up high. Amazingly, there is very little sound inside the coach or at ground level. Maybe someone else can add more. Hope this helps.

My wife even hated the gas she could smell if the Onan had run earlier in the day.

I converted our Onan to propane. There is a kit available. Runs great. Has a shutoff switch that shuts off the propane. Runs off vapor from a T after the regulator on the tank. Then it has its own regulator.

Got the kit here: http://www.propanecarbs.com/small_engines.html

Out of curiosity - how will a propane conversion remedy either of these factors?

Exhaust from a propane fueled unit will still contain the CO and other NOxious gases that you don't want around plus there's no difference in noise based on what fuel is in use.

I suppose my experience with Onans is atypical as I do not get exhaust smells inside the coach nor do I perceive it as particularly noisy. I built a gen-turi out of an 1-1/4" EMT elbow and a piece of downspout pipe but I only use it when I go to the racetrack as a courtesy to my neighbors in the camp lot. I carry two CO detectors at all times and neither of them has alerted when the Onan was in use either with or without the gen-turi in place.

Jim,

I'm sure that you would not understand, but some side valve (aka flathead) engines that are not decarboned regularly produce an aldehyde that some people find objectionable at very low very low concentrations. As propane is use as a gas fuel only, it is less likely to produce this. That and the lack of a possible liquid spill are why it is used for indoor power equipment.

FWIW, I've seen a couple of Honda EV gensets on craigslist fitted out for propane.
