For a recap. I take my RV to a Cummins/Onan shop in Greensboro NC. Took about 1 month for the replacement tailpipe to get to the shop. I took my RV in to have it installed and I get a call back saying the muffler is damaged and it has to be replaced. The bad part is the generator has to be taken out to install the muffler. I called both Thor and Cummins/Onan in Elkhart Indiana. Both agreed the generator would need to come out. Here's my question. Cummins in Greensboro quoted me $2100 for the labor and parts. Both Thor and Onan in Elkhart thought that was about $1000 too high. I was told by Onan Indiana it takes about 1.5 hours to remove a generator. 2 hours tops. Not sure how much a muffler is and the tailpipe can't be too expensive. Bottom line Onan Indiana said if they did the job it would cost approximately $1000. They charge $130/hr for labor. So 4 hours to uninstall/install generator. 2 hours to install muffler. Muffler cost ?? will go with $300 and tailpipe $200. This all comes out to $520, labor for gen. $260 for muffler labor. Parts and labor cost is roughly $1280. Am I getting ripped off by the Onan dealer here in Greensboro? It would probably be cheaper for me to drive to Indiana to get fixed but not feasible. Thoughts? Thanks.

I think you answered your own question by pointing out how the numbers don't really make sense. Good luck

155-4661 is the muffler, how bad is it twisted? The generator only takes about an hour to drop. One hour to put back, if you know how and have equipment. It doesn’t HAVE to come completely off, just enough to get top and sides off. I think the muffler just over about $200, but $300 is a good barometer.

There is lots of other dealers and even a factory store in Charlotte or even Freightliner factory store in Gaffney.

Yes, I think their quote is high.

Well, new exhaust pipe is on but they mounted too low. When the coach is aired down the pipe is touching the ground. I have since taken it back and they said they will fix that. The whole thing cost $1245 which is more in line with what I and everyone else thought the cost should be.

not sure how it can be installed too low. are you saying the opening of the exhaust pipe touches the ground when lowered ?? or the whole pipe from the generator ??
Did they install a generator exhaust hanger at the end where it extends from the side of coach ?? If not the pipe is too long without one and it will drag when aired down.

Can you post pictures ?
Would like to see exactly what you are talking about.

If they installed the correct part and did it correctly is should be exactly like the old one was. Something is wrong if it's not. I'd have them fix this one but I wouldn't give them my business in the future. I use the one strike and you're out rules when it comes to factory authorized repair facilities, they should know exactly what they are doing and it does not look like that is the case in this instance. Yep, not much patience with mechanics that make things worse than they were before they got involved.
