Justice has given you some good advice above. I think I'll install a bypass switch for the a/c fan <img src="/forums/images/graemlins/kewl.gif" alt="" />

Just to clarify a little, 97-99's came with 4.272 gears and not 4.1. Still crappy though <img src="/forums/images/graemlins/notooth.gif" alt="" /> 4.90's would probably be a good upgrade, especially if you want to run bigger tyres. having said that I run 32's with 4.272 gears and I only notice a small power difference when the truck is loaded with kids etc and we're going up a steep hill. Normally switching off the O/D for a minute does the trick <img src="/forums/images/graemlins/kewl.gif" alt="" />
