I've been looking for a '02 4x extcab long box wht with the 8.1l/allison pkg. I have found 2 (at same dealer lot) low miles under 20k. Both are nearly identical. These trucks came from the same company fleet. What can I look/listen/smell for on the 8.1 ally to get the best of the two, as I intend to buy one of these two trucks.

Post the VIN's in the VIN forum here and you can see the warranty history.

You're going to need to repost that here: http://www.dieselplace.com/forum/forumdisplay.php?f=72

Thanks Max Power I just got sooo excited about these trucks and the info available on the web that I posted in the wrong spot.

Here is the info you requested http://www.dieselplace.com/forum/showthread.php?p=581192#post581192
