I see similar threads regarding generator slideout , but I think I may have a different situation. Coach has a 12.5 Kohler / Perkins . I was finally able to get the gen slide moving , but it stopped after a few inches . Sliding it back and forth it got better by degrees , but still stops well before the engine is far enough out to service . It's obvious that the exhaust is the hang up , bulkhead is flexing when I tug on it ( not a lot of force left in me ) . It appears that the pipe from the manifold slips into a larger pipe which is flush with the bulkhead. Is there a coupler that has to be unbolted ? I can find no mention of anything in the coach manual. There is a stay at the rear of the engine that has been broken for a long time , evidently someone has been down this road . 
I read the post about unbolting at the silencer , but the pictures appear completely different to my configuration.
Thanks, Chris
