I've got a Roger Brown 2" and love it. No problems with the install and no added squeaks or rattling. I think the only difference with the 2" over the 1" is you have to lower the radiator but Toyota already has holes that are in the exact location so I didn't have to drill any more. Oh and the shifter linkage has to be adjusted but no adapter is needed. Also disconnect your battery terminal leads before lifting because they will pull. The sparetire carrier won't be functional anymore so you might want to remove the spare and reel the holder all the way up.
