Nice rig @Grantskys17. I agree with @Box Rocket - nothing wrong with wheeling a nice rig. I don’t get why there are people here who talk sh1t about mall crawlers but they also give you crap for wheeling your rig because “it’s too nice”.
Anyway back to your original question, the “best” option for a rear locker would be a selectable one like ARB or Harrop but since you have a semi float the Harrop will not work. The “best option on a budget” would be an auto-locker like everybody here has mentioned.
I myself have Harrops front and rear and I love them. But maybe I should sell my 80 get a Cherokee instead?
