I read all the info on the websites and gave it a try and it worked out easier than I thought . I will do the final adjustments tomorrow but right now it seems to work which gives me a feeling of acomplishment .So far I am in to this project for $23 so with a couple of brackets and some paint I am still going to be ahead of the retail price by at least a bottle of good wine which I will use to celebrate

There are several sites that tell more or less how to do this . what I did was get a piece of 1 1/4 exhaust pipe bent at 90 degrees and used an electrical conduit connector to connect that piece to the original exhaust pipe then I got 3 straight brackets and a 3 in pvc pipe connectoe and screwed the connector to the brackets and then screwed the brackets to the exhaust pipe ( I am going to take the screws off and weld the brackets ) then I added a piece of 3 inch pvc to the adapter that would reach above the roof
the trick is to get the 3 inch pipe the right distance fron the 1 1/4 in cpece I think it is suposed to be about 1 1/4" --1 1/2 " apart
hopefuly these pictures will show up here

I made one using an electric EMT 90% and a length of 3" light weight pvc. I soldered 3 pieces of 3/4 copper tubing to the emt for spacers and with a little fine tuning with a hammer so they slip into the pvc. My genny is located up front with the exhaust coming out just below the mirror. So a bungee holds it in place.I cut the pvc n half for easy storage.

That was VERY cool, Bob, thank you for the pictures! Looks like it does the job and the best part, it's a fraction of the cost of purchasing one.... well done!

I still like the Original Genuine Article best.. Some of the home made units can over heat and melt (though in truth I do not think they should if well designed) and all of them are heavier.... The Genuine article is way lighter than the same length of PVC.

Still.... If you wish to park next to me at a rally (So that I am on your generator side) I very highly recommend having one. Home made is just fine.

I made one similar to that, but have not yet had an opportunity to use it extensively. Worked great in a 25 minute test run, though.

One difference in the design i used: my PVC portion overlaps the metal portion just slightly, which keeps the exhaust flowing up the tube in a breeze while still allowing plenty of cooling air to enter from the bottom. My coach isn't near me now or I would post pictures.

The basic pipe construction is pretty simple - the creativity comes with the method of supporting the pipe in a vertical position. Depending on where the pipe is in relation to the side of the RV, and your willingness to mount some sort of bracket to the side permanently (I was not willling), this can be hard or easy to do.

this is a sort of good news bad news. the pipe goes past the bedroom window so now the exhaust is well away from the window (good) but now I can't put the awning out if the exhaust extention is up (bad ) but there is a factory type hook for the awning right where the pipe goes so I don't have to put any hook on the wall (good). I am going to put a bracket from the extention to the chrome railing on the roof. by the way I used thin wall pvc which I figure is pretty light but very durable I dont think I would use the kind of drainpipe I have on my house it bends and dints way to easy for me.
