can someone tell me why dodge lists an hour meter for 2003 but not 2004 or is their one, and i dont know how to work it?the dealer doesnt have a clue how or why their is not one. i put one on my 98. 5 and is really helpful, i average about 40 mph to 1 hour it is helpful to know when to change the oil and filter,also fuel filter becuse i do a lot of slow driving, and idling. does anyone know the rule on this i just guess? your help would be appreciated. thanks
