i had in mind a 02 one, that my friendly dealer has (i purchased few silverados from him) but, what you have written about the seal and rear window changed my mind. I grew up driving yj's tj's and lately an xj. all of these vehicles were lifted and went through a lot of mud. I just got a little bit tired of seeing water and mud in the cabin, and if i know it leaks, or there is a chance it will-I dont want it

I assume 4.11 came with Towing option? Are trannies in avalanches same as in silverados? will fail sooner or later, or different model? i assume the fuel pump is probably the same, as it is built on a suburban frame. Had few of these fail on the trucks i owned.
I would like to thank you for writing all this to steer im in right direction

that is a lot of info, and time you took

Thanks
I have one question, how is the stereo in these trucks? is it same as in 2003 silverados and requires a special adapter to install an aftermarket unit?
