Was considering setting up a sort of exhaust extension for the onan, to move the exhaust fumes farther from the coach to keep my wife happy. Was thinking along the lines of welding a threaded collar onto the Onan Exhaust muffler outlet, and a female threaded collar onto a length of flex tube similar to this:

Should be able to just screw it on like a garden hose when boondocking or whatever, then unscrew and stow when not needed.
Is anyone doing this already? Any opinions on if this is advisable?
I've considered the added backpressure that it will put on the engine, and if you go with a slightly larger tube, and keep the run below say 15', I would imagine it would be negligible. Plan to monitor some exhaust/head temps with it uninstalled and installed to see how much it raises temps. Would obviously also keep the tube out of leaf piles, etc. to prevent fires/heat damage to anything.
