Here I am at the Albuquerque Balloon Fiesta in a crowded lot boondocking with dozens of other coaches. I figured it would be neighborly of me to redirect my exhaust fumes from the side of my coach but I didn't want to spend hundreds of dollars for a Genturi. My solution -- I bought a dryer vent hose at the hardware store for around $12.00. I know some of you are thinking that I can probably afford the Genturi but frankly, this was much easier to setup than a Genturi and it's much easier to carry around in my storage compartments.It's been working great for the past couple of hours. What do you think of it?POST-CAMPOUT UPDATE, 10/15/16:I'd like to update everyone on the results of my $12.00 exhaust redirect. I ended up using it only on Friday, Saturday, and Sunday. On Monday, half the campground cleared out and we were left isolated over 100 feet from the next RV. At that point, the cheap dryer vent had cracked and was not suitable to transport the exhaust plus the winds had kicked up quite a bit. This was especially a problem for the VIP lot because it was at the top of a hill and the winds were funneled into us.Because of the high winds, broken dryer vent and lack of neighbors, we simply unhooked the dryer vent and went au naturelle. Had we needed to, we could have patched up the vent with aluminum foil but there was no further need.Overall, I'm very pleased with the results. Obviously, a real Genturi would be more durable, and would look nicer. But for a one and done cheap solution, I'd highly recommend it. I'm guessing the dryer vent, properly installed would be as effective as the Genturi, properly installed.

When I had my MH I made one out of 3" pvc cut it into 3 1/2' sections and made an adapter to the Gen exhaust from conduit for about $35, a lot cheaper than the ones at CW

The Genturi is good, especially if you are going to be parked in tight places very often, because it vents to the top for the draft. I use a piece of flex exhaust pipe just to get exhaust further from the rig. It works well, and just rolls up in my basement storage when not in use.

The dryer vent seems like a good idea, but with the flex pipe I use, it does seem to get quite hot. Might keep a good eye on the dryer hose for overheating, melting, or fire. If it is loose fit on the exhaust pipe, that does allow a bit of cooling air to be drawn through with the exhaust.

I could feel some leakage where the Genturi elbow was fasten to his exhaust pipe. There were two joints as he had to use an adapter to increase the diameter of his small exhaust up to the size of the Genturi elbow. My Presidential rig would have worked better on his small exhaust as it does not require any adapters.

My Genturi does not require any adapaters to connect to the Onan diesel generator exhaust.

It ran very quiet and no smell for a very closely packed campground.

Of course, a 15-30 MPH wind out of the south probably diffused any smell too.

Ivylog, I ran a quick test using the aluminum downspout (lots of quick rigging - need to make it work for testing) and used the 4 gas detection meter from our fire station to test it. Lots of interest there as well, since there is group of campers there as well. With a 1" to 1 1/2" gap we got essentially a zero reading. Right now I'm calling it safe.
Will have to do more checking later on when I build the mounts.
Found I have a leaking lift pump and needed to fix that first before our last outing next weekend. That was an adventure all in it self!

I know the difference in the smell of a gas generator and my diesel plus he would run his from 3-6 PM and I would not start mine until after 7PM for less than an hour. Most of the time I was upwind with a slight breeze.

I would say then he was running rich.

Gasoline or Diesel? Upwind, Downwind, Crosswind? Smoking?

Probably smelling your own. Lol

Hot Air Rises!

Which do we think would "share" more exhaust with our neighbors or ourselves?

Ivylog, love your setup.
I've thought about doing something when we retire this coming spring, but we haven't had the need to sit long times with just the genset yet. I now have a simple solution thanks to you and I may paint mine black. Best part is the DW thinks "practical" as well!
Just because it wasn't bought all nice and premade, doesn't make it any less useful!

I agree I should paint it black... would not show the dirt from the propane bay where I store it. I was surprised how much exhaust smell I got from my neighbor this past week at the balloon fest with a factory Genturi.
