what is the best year to look for?

[TBlume]

I am looking for the best year of 2nd gen truck, I need at least a club cab with the big kids I have, (both me and the wife are 6 footers) and I know the cummins is for me.

Not to picky about 4x4 or dually, 12 or 24 valve. I know I want the manual transmission, and will try and spend less than 15 large.
what do I need to look for, problems, good things, etc..? I figure two wheel drive will give a bit better economy and lower the entry fee a bit, and maybe ride a little nicer.

what are your opinions and first hand knowledge?

thanks in advance,
Tim
