I have a question about these extended exhausts. Being that CO usually pools in lower places, like basements (the reason that I have a Co detector in my basement), what is the effect of the discharged gas if you have the roof vents open?
I would worry about the gases coming in, especially if there was no breeze and the you were in colder temps.

FAR FAR less chance of CO poisoning running the exhaust up than there is letting it pool underneath a vehicle. More than 1 has not awakened the next morning with no exhaust standpipe due to CO fumes building underneath and seeping inside the RV
This might be a dumb question, but could the long pipe that runs up the side of the RV be made of thick PVC or ABS? Or would the exhaust be hot enough to melt the plastic?
The Genturi IS plastic pipe. Mine gets to about 100 degrees when my Onan QD 7500 diesel generator is working to run both of my rooftop AC units. Never what could be called HOT.
do NOT use a plastic downspout. works fine with the genny running without a load, but will melt when you load it up. personal experience talking here...

The key to keeping the plastic pipe cool is the way the air gap is designed where the elbow blows the exhaust into the pipe. If you are going to build your own take a close look at a Genturi and specifically the way the exhaust elbow is placed in relation to the plastic pipe.
Note to RV Designers. Run the generator exhaust through the roof near or into the diesel exhaust also through the roof.
Everybody gets quiet and no diesel exhaust no much sound drifting around near the ground and into neighbors coach and around the campfire.
Nice work mph_medic, that looks like a clean setup!

The density of carbon monoxide (MW=28) is nearly identical to that of air (29) (i.e. it doesn't "pool in lower places"). However, CO is a product of combustion, and hot (exhaust) gasses rise due to convection. As a result of this convection, having the generator exhaust exit above the roofline is far safer than any location below the living space.
CO detectors should be installed in the locations where people breathe the air, and at (approximately) the height that their mouths & noses will be located... If you sleep or spend time in your basement (RV or home), then it makes sense to have a CO detector there, but that should be in addition to the one(s) in the living space(s).
