Stephen, Have you ever given any thought to extending the wheelbase on your rig? After viewing some video of K5's in action at Disney Oklahoma, I started thinking about moving the rear axle back. I am thinking about extending the wheelbase at least 10". While doing this, I think I should change to a 3 link setup in order to bob the rear of the truck. Do you have any suspension systems dreamed up? What is the recommended shock travel for the rear? Thanks for your input.
