I know some of these aren't really mods, but they are if the truck didn't have them when I bought it <img src="/forums/images/graemlins/lol.gif" alt="" />
A few of the best...
Manual front hubs (awesome)
Marlin Crawler shifter seat and end cap upgrades (shifts way better now)
A "new" old drop-in bedliner (no more bed destruction)
A working stereo (of course)
Tint!!! (nuff said)
I flipped the tires around to show the OWL...much better <img src="/forums/images/graemlins/smile.gif" alt="" />
And definitely all-weather mats (a car-sick cat of mine made this all too clear the other day...thank you rubber mats!!!) <img src="/forums/images/graemlins/barf.gif" alt="" />

All of these mods make life way better in the truck than when I got it, and it wasn't exactly tough to begin with <img src="/forums/images/graemlins/lol.gif" alt="" />
