Hello,
Love what you have done to your rig. We have a 1985 sunrader factory 4x4 and want to do something different with the wheels to get same size rims and tires all the way around. Tire availability is severly limited with the current set up. I'm going back and forth w.r.t. new 16 inch duallys with adapters, same size rims but different style on front (not a flipped dually). I like your approach going to single tire in back. My only concern is that airing those up to support the load would result in a harsh ride. Has this been an issue for you?
Thanks!
