if the truck is your dd id go 4.88 gears and 33's. if a year or 2 from now the trucks going to become a dedicated wheeler id suggest 5.29's and 35's. i have 2 toyotas set up like this.  my dd has the 4.88's and 33's it gets better mpg and has more high end power. if your not going to re gear your axles run 31's. i dont care what anyone says without gears pulling anything bigger than a 31 on a 22r/re daily driver sux! and its hard on your transmission. thats my opinion. you can go a long ways on some 33" tsl's
