Add me to the '03 - early '04 recommendation list too. Though I mainly use my '03 over the road and don't tow, I've had very little problems with it. I upgraded from a '98. 5 and really liked the extra power and the fact that the engine was A LOT quieter. My wife has an early '04. It's her first diesel and she loves it. Haven't had any problems with it either. The standard '04 engine is the same as the '03 HO, I believe. The only two things that I know to look out for are the lift pumps (I have about 99K on mine with a FASS or Air Dog in my near future) and the 47RE/48RE automatics tend to have some gear hunt issues, but both issues are easily remedied. When I added my Banks Six Gun package, not having a catalytic converter made replacing the exhaust a whole lot simpler. Just my $0. 02 worth.
