Are the 2004 CH and CX frames the same right down to the drilling? Or are they the same width and general layout but differnt lengths and hole drilling?

OK, first thank you for the information. If I have this correct the breakdown goes something like this; • CH & CX are 2004 and down and pre Volvo • CXN & CHN are 2005 and up with the Advantage chassis (Volvo) and AC engine • CXP is 2005 and up Advantage chassis and Pinnacle cab and MP7 engine • CXU is 2005 and up Advantage chassis and Pinnacle cab and MP7 or MP8 engine with DPF • CHU is 2005 and up Advantage chassis and Pinnacle cab and MP8 engine One more question, Why is there different chassis widths? What are the chassis width for the pre-Volvo and the advantage chassis at the front (at the bumper)? Thank you for your help!

Oh come on there has to be someone that knows this. Please help me out.

Hello, I am new to this forum and like what I see so far. I am hoping there is a Mack guru out there that can answer my questions. I have been trying to figure out when the frame width changes on the Mack CH and CX models and what years they took place. Also why is there a CX, CXN, CXP and CXU? What are the differences?
