Word of CAUTION

Just a word of caution:
I own a 2005 Coachman motorhome on a Feightliner chassis with a 300 HP cummins with 34,000 miles on it. Bought it new.

I'm now going on the 4th, yes, number four turbo and 2nd exhaust manifold.
From what I'm told, the issue is that this is a mongrel motorhome setup so the turbo and manifold are near impossible to get. I guess the wastegate is part of the turbo with some variable contoller that keeps crapping out. Looking for the manifold has netted nothing, Cummins is contacting the manifold manufacturer to see if they can get/make one.

Moral of the story: DON'T buy a 300 CUMMINS on a Freightliner chassis MH around 2004, 2005.
