2000 versus 2002 service manual, any big difference?

[Pit Bull]

I had a 2000 service manual for my old truck and was wondering if there was any changes that I needed to be aware of between the 2000 truck and the 2002 when using the manual. I guess one difference that I am aware of is they did not have the HO engine in 2000 and my new truck is an HO Can anyone think of anything else?
