I love my '03 and just joined the 100k mile club. I did what I said I would never do and bought a first year run. BUT, the body was 2nd year from the 1500 and the automatic could only get better. The 48RE has been an improvement and has been "very very good to me" with regular (15k) maintainance and a little tweaking. If you have the HO auto, it will have the 48RE and 11. 5 rear end.
Some things to look at for all years;
-A/C blend doors (my recirc door is droopy and is not closing completely since around 90k)
-Ball Joints (I still have stock, but others have had issues. )
-Power steering buzz in pedals and steering wheel (Damper TSB fixed mine)
-Death wobble (My problems have been the 315 BFG's with lots of balance weights and/or low air pressure)
-Don't let the dealer do the stupid reverse recall! (I may never take my truck to the dealer just to make sure I don't "get" it)
-American Axle maintainance (I just bought a 5 gallon pail of Royal Purple 75w90 and change it when I do the Trans. at 15k)
-The taillight connector system is ..... lacking (Go buy new glass based bulbs and dielectric silicon at NAPA. )
-Poor headlights (I swear by Silverstars. Are the Ultra's any better?)
Stupid Little things that happened just before 100k;
-At the first cold snap this year my hood supports gave it up and the hood nearly took my head off.
-A motor in the drivers power seat went out. (Mopar doesn't just sell the motor

, so I went to the junk yard. )
-Had to change the stock front brake pads. :-laf (Paid the extra bucks for the OEM pads, threw em on, and kept going. I try not to mess with something that works. )
-The water pump went out. (Hmmm, pay the dealer the $100 deductable plus rental or put it in myself and flush the cooling system properly for around $100?)
So based on this being the best truck I have owned and MY perception of the 04. 5 and up models, when/if I turn this one into the farm truck, I will look for an 03 - 04 with low mileage to replace it. Sooo... .
Have you bought it yet?
