Diesel burner noise vs. Propane noise

[TJ&LadyDi]

Sure does! Our 2018 does not have a muffler installed. I wonder if mufflers were discontinued starting with the 2018 production run, or whether it was a model-by-model thing? We have considered adding a muffler, though our Oasis burner isn't much louder than a lot of propane furnaces.

I looked under my coach for some reason while walking the dog. It appears I may in fact have a muffler???

@Neal … you just saved a pile of money!

Over on that other forum there is a thread about adding a muffler to the Oasis piping. I just did that to help cut down on the noise. Here are a few pictures. I used a Jones Exhaust Turbo Tube Muffler ATT18S-3 and Vibrant Performance Exhaust Seal Clamps 1163. Now I just need a volunteer to camp really close to me to see how it works.

Finally had a chance to field test the new muffler and am very happy with the results. Did not have a noise meter, but the sound is noticeably lower and now I would not even feel bad if I had to camp next to me! Painted the main body black with this high heat paint to help things blend in.

I have a hunch that setup is better than what Newmar installed on mine and anything pre-2018. Nice job!!!

No "hunch" here, @FLSteve; that's the nicest install I've ever seen. Newmar usually does pretty good work, but not to that level. Well done!
