PACCAR MX OR ISX?
Looking for a little advice. Am going to be purchasing a new flattop 389 Peterbilt, been hearing good about the Paccar MX motor and the Cummins ISX. Just hoping you guys might be able to offer some guidance on making my decision. Any input would be greatly appreciated as this will be my first new truck after the last five having all been purchased used. Kinda nervous about a buy of this dollar amount and want to avoid any potential mistakes. Thank you in advance.
