I find my Oasis system to be loud so adding a muffler

For no reason other than curiosity. I wish we had 2 electric elements on our Aqua Hot. My wife and I can typically take back to back showers on electric but I always take the 2nd shower so if anyone runs out of hot water, it's me and I can just holler for her to turn on the diesel. I love the fact that we have electric heat in the floors. It is such a nice heat and works well down to 40 or so. We don't use the Aqua Hot much as a result other than making sure it runs a little every now and again so that it doesn't sit to long without running.

Thanks again

My sister has heated floors in her Phaeton, which I wish my Ventana had.

I'm not sure if there's has a problem (actually, it's had a BUNCH of problems, Tiffin replaced the entire unit and it still boils over and loses all fluid, which has everyone confused), but with their first unit, there was a very loud exhaust fan that came on before the burner. That was louder than the equivalent (if there is an exhaust fan on the Oasis) on my Oasis, but I find their "turbine" sound less annoying than my "generator" sound.

Also, the tiffin internal fan registers are quieter than the newmar's when using it for heat.

So, pros and cons for both. That said, I really like the two heating elements, so I rarely use the burner (other than periodically running it to make sure the diesel is moving and doesn't gel up or whatever happens) except in winter.

I would be happy with either vs. going back to propane like I had in my ACE.

Wow! Two units doing the same thing. Must be something in the way they plumbed it up. Hopefully they get that figured out soon. I don't know if they are at a dealer or in Red Bay. I can't say enough good about service in Red Bay. I was blown away and glad we went there. We didn't have anything big on our list and had them do a couple modifications and they didn't charge us a Penney. The bus was under warranty at that time.

Red Bay. Only thing left is the wiring harness I think, possibly something shorting out. Basically overheats and boils all the fluid out.

They feel the same about Red Bay service. Had a LOT of problems with their first Phaeton (2012), but because Bob Tiffin fixed it all, even when years out of warranty, they bought a second one.

I came close because we are only 5 hours from Red Bay, but couldn't find a floor plan we liked as much as our 4369.

Wow! That's scary! Hopefully they get it figured out before the thing causes a fire. Newmar makes a great coach. It was between the Bus and the Dutch Star. Couldn't find the floor plan in the DS and North Trail in Ft. Myers would only come down 20%

Can we get back on topic here please.

I was looking at the two sides of the burner box and I wonder if you applied dynamat to the sides, would it deaden some of that rumble. I don't think the side walls are used for cooling in anyway. Maybe a question for ITR Oasis.

You might be on to something Dynamat does wonders in many different scenarios.

FWIW: I was just under the motorhome, verifying measurements and such prior to ordering a muffler as has been described above, and discovered that the Oasis exhaust pipe hangers had been installed so that the metal parts of the bracket were touching each other and the motorhome frame. There was no rubber isolation between the pipe and the motorhome! As well, the hanger at the exhaust pipe end had self tapping screws that had stripped out and were loose. A quick repositioning of one hanger and replacement of two bogus screws with nuts and bolts has provided a noticeable reduction in vibration and noise.

Great find be we did not experience of of these clearance issues before or after the install.

Take note the muffler I listed in my first post is the wrong link I reposted the correct link later in the thread.

I measured and have the room so might as well go with the longer one. Will call Summit and see what I can work out on a return and switch.

Finally got around to installing mine. Went with the 18" length muffler as Summit had no problem switching the 12" for the 18". Now I just need a volunteer to camp really close to me to see how it works.

Posted a few pictures of how it looks. The last two were before it was installed.

What kind of paint should I get if I want to paint it black. Maybe the Rustoleum engine high temperature spray paint. Saw that at Home Depot.

FLSteve

PS … oh shoot, just remembered I forgot to drill the two 1/8" drain holes in it. Guess I better head back out there.

We leave tomorrow for a 5 day trip with 30 amp power, which means the Oasis will be running at night. We'll see if the exhaust helps with the neighbors.

LOL I read the response from my email and was going to remind you but I see you remembered.

Rustolium would be great probably better and more durable than the enamel paint spray paint I used.

They are going to love you

Does anyone have any thoughts about raising the Oasis exhaust pipe to provide a little more clearance? I purchased an 18 inch muffler like FLSteve did but now that I see it, I'm a little concerned that if I install it, I'll risk catching it on some of the rougher roads we tend to end up on on our way to boondocking spots. Can the whole exhaust pipe be raised without risking overheating the underside of the coach?
