2 for - if it isn't broke don't fix it. I don't mind reading about both. Heck you might learn something that would sway your decision in a purchase way down the line. Like the cheap handling fixes we hear many of the gassers complain about. Really don't get the problem all of a sudden.
But there are differences other than brakes and engines. Lots. I don't know too many gassers that are loaded up with suspension benefits, steering, frame benefits, and all the fancies you can get on the inside. Eletrical stuff alone would boggle the mind of most class A gassers. Heating systems, etc.
But I vote leave it as is.
