Brother I installed everything, I’d know if I put spacers on. Rear tires are 35x11.5, fronts are 35x12.5. Inner wheel is +115 offset, outer is -198.
I haven’t hooked up to the trailer yet but I’ll definitely get you some pics for reference when I do, it’ll be by this weekend. IMO, if you leveled with Don’s 2.25” or Carli’s 2.5” front coils and threw Carli’s 1” rear billet block In the rear you’d be way good. Depends on the height of your 5th wheel though I guess. My current toy hauler sits extremely high, compared to my previous 5th wheel. Everything is relevant.
