Well, the really only reason to convert it is to make it easier to drive around. It is my primary mod of transportation right now...as for ever selling it...heck, I plan on running this thing into the ground...
My heart is not set on 35's...I wouldnt mind a set of those new 20's that are coming on the newer superduties though. I have no idea what their size is.
I do want a bit more suspension travel for my...well...more spirited driving days...
