Hi,<br/><br/>I have a '98 Concept with the generator located on a front slide. I purchased the coach used and didn't realize that there was no exhaust pipe routed from under the coach. The exhaust pipe just pointed straight down at the ground from one side of the generator. I've replaced the original 17.5kw Powertech with an Onan 10kw quiet diesel. Now we can have a conversation...
