I have a 6 week old 2001 4 x 4 2500HD QC, 3:55's and automatic and have yet to get an answer to the first question I had about this truck. It is equipped with cab clearance lights, however, they are the old style "high profile" type found on pre 99 trucks. It was next to another 2001 on the lot in Nebraska, this truck also had cab clearance lights, but they were the new "low profile" type. I asked the dealer about it and received the answer "they just come both ways". Since that day I have seen one other 2001 with the "high profile" lights all the others have had the newer "low profile" lights. It's not a big deal but what the heck is Chrysler doing?
