Something to do with the flat load floor that enabled them to class it as a truck.
Most Chrysler Products between 1998- 2010 could display codes by cycling the ignition key. Turn key to on , then off, then on , then off, then back on. The odometer display will cycle through any codes in the PCM.
Go American with the engine. A Hellcat or the 650 hp LT4 would be a good starting point. Plenty of power, awesome sound, and (in both OEM's case, a 5+ year, 100000 mile warranty). Plus, once Tavarish gets his hands on it he can replace coil packs for $34 instead of $1800.
