This summer I plan on doing some dry camping with little or no electricity. This will include a rally. Should I consider a generator exhaust extension up the side of my MH or is this not necessary? I have not seen any recent posts on this. I would appreciate any comments from anyone who has one.
Thanks; Don

In my opinion, they are a good idea and should be used. We bought the one from Camping World about a month ago and it seems to be a decent quality unit.

Onan states specifically that exhaust extensions should not be used, as it greatly increases the chance of the exhaust entering the motorhome.
<BLOCKQUOTE class="ip-ubbcode-quote"><div class="ip-ubbcode-quote-title">quote:</div><div class="ip-ubbcode-quote-content"> Statement Regarding Exhaust Extensions
Cummins Power Generation, manufacturer of Cummins Onan generator products,
does not endorse the use of RV generator exhaust pipe extensions. Like all fuel
burning devices, engine-driven generators emit carbon monoxide (CO) which, if not
safely handled, can produce serious injury or death. Cummins Onan generators, in
conjunction with RV OEM installed tailpipes, are designed to meet RVIA standards
for safely handling exhaust gasses while minimizing noise and maximizing generator
performance. Improper modifications to the exhaust components can result in
unreasonable hazards to the vehicle occupants.
Cummins Power Generation has been unable to this date to identify any
commercially available exhaust extension kit which meets reasonable standards for
safely handling exhaust gases. </div></BLOCKQUOTE>

Don, the Genturi is a great idea when you are in close quarters with other RV'ers, generally at a rally. The generator exhaust can get overwhelming in that situation.
Onan's comments are for those extensions which are not engineered well, or home brews, resulting in back pressure forcing fumes into the coach. Other systems, such as the Hydro-Hot/Aqua-Hot systems actually recommend the use of the Genturi exhaust system, to get the fumes away from the side of the coach.
The Genturi is engineered well, and won't result in backpressure in the exhaust.
Here's a test. Take a very small piece of paper, and place it at the bottom of the chimney of the Genturi. It should be sucked up thru the exhaust and out the top in a fraction of a second, with the generator running.
I would not worry about using this system.
But if you are just boondocking with no near neighbors, I don't think the need for the unit is as important. Just keep the windows closed on the side where the gennie exhaust is discharged.

We last used our Genturi at the FMCA Redmond Rally we attended in August 2007. We have used it other times when we boondocked. My comments:
It does move the exhaust up and away from your coach. At the rally, I was shocked that so few of the other rally goers had a Genturi. We used ours when we recharged our batteries and used the microwave for dinner. Because others around us did not have one, there was so much exhaust around us that we had to shut our windows and run our AC. Next time we go to a rally, we'll stay in the electric section (powered by large generators). Finally, when we had our Power Tech generator in for routine service at a generator specialist, I asked if they had seen any problems caused by the Genturi. The answer was NO.

Look around on the internet, I picked up one last week from a fellow in Nevada for $50. Used only 5 times, and it's a gem.
Take a look around before spending $140, may save you a dollar.

My previous two motorhomes exhausted out the rear, so there was no problem. My present motorhome generator exhaust is on the driver's side just in front of the front wheel. In a rally, it would exhaust right into my neighbor's door. I bought a Genturi and I'm very pleased with it. It is not really an extension because the exhaust pipe and Genturi inlet are separated, so there should be no back pressure.

We dry camped at Christmas time in the desert and had our carbon monox detect go off a couple of times from extensive generator use.
I think the extension is a good idea...
