Generator exhaust
Hello PC – I’m installing a Martin Generator on my XL and need some ideas as to how/where to run or mount the muffler since it appears that it may be not enough ground clearance underneath. Any suggestions are greatly appreciated!

On my coaches the exhaust pipe was run back to the area where the tag and drive axles are and then the muffler can be raised up in an open area, before continuing the exhaust pipe to the rear or side exit.
Keep the exhaust pipe away from the foam insulation, possibly adding a heat shield or an exhaust pipe wrap. I even turn the pipe clamps so the threaded part is pointing up or to the side so the clamp doesn’t hang down any more than necessary.

Ok thanks that sounds logical, I will take a look at that. One local guy suggested put tthe muffler inside the compart with the generator. What are your thoughts on that?

No, no, no………….You want to get and keep heat out of the generator compartment.

Ok thanks, that was my thoughts also…

Year, chassis type, and converter in your signature would help the other members give you more concise help. Are you converting an older seated coach? Does the coach have an existing generator.
I met Jim Martin a few weeks ago at PRI in Indianapolis. I found him to be a very nice and interesting person. Very, very knowledgeable and sounds like he and his company have a long history in the motorcoach business.

Thanks – Yes I have an older 1989 Lemirage XL that’s being converted from a seated coach. No there is not a generator onboard already.

If you are starting with a clean sheet of paper you are already halfway done. Locate the heavy stuff as far back as possible, such as putting the tanks for water and waste and the generator in the bay immediately ahead of the drive axle. You do yourself a huge favor by keeping the weight off of the steer axle, and in the case of generator exhaust you can exit out the bulkhead on the drive axle side of the bay eliminating a lot of the concerns about ground clearance and a hot exhaust mounted up close to the bay floors.

Thank you all for the valuble information. Keep it coming!

Does anyone happen to have a picture of the generator muffler installed near the drive axle?

DHS,
If you are in the early stages of converting your coach one of the best things you can do before you cut a piece of wood is to go steal ideas.
You can start by looking at photos of coaches for sale on this site and others. Every time you get a chance look at finished coaches. Depending on where you live you may have access to a large number of coaches or maybe you live near members who are willing to show you their coaches.
Prevost conversions have been around for a long time and over the decades the professional converters have developed some very good floor plans, systems designs, and use of space. We who have been traveling in our conversions for a while have come to appreciate just how well thought out these conversions are.
Do we like everything? No. Every one of our coaches is a compromise that does almost anything an owner can want, but is not best for a single purpose. We can run from power pole to power pole or dry camp, but none of our store bought coaches are perfect for any one specific use. That is where you come in to bias your design to your specific needs. But do not ignore the efforts the converters have made to create fantastic coaches. Copy them when you can.

DHS,
The exhaust on mine goes out the bottom of the Gen bay, 3rd bay curb side, then the muffler is as Jon said, in the cavity between the drive and tag axles. and then, the pipe continues straight out back under the bumper. The opposite side,,,,, the exhaust for the Aqua Hot does the same thing, just on the road side.
