We got an '04 AF990 in late '05 and saved quite a bit versus buying new. It is a heavy bastard, but I have a dually so it holds it pretty well. Here's a pic of the combo truck/camper/trailer:

This is the email I received back from my district representative Skip Priest (he was quick to return my email which was great):
So email your Senator that represents your district.

There's a place in Auburn called Pro Exhaust or Performance Exhaust. They are on 22nd Str NE just across the street from the Chrysler dealership. They are in between Auburn Way & E street. They do 4" exhaust on Diesels.
