The 2008 Wildcats had two different front cap designs. The early models had the old front cap and the later models had a new cap that was designed for standard bed (6 1/2 feet) pickups.
Here are the two front caps for 2008. This first one, my 2008RKBS, is the old design and you will definitely want a slider hitch. Naturally they changed the front cap just a few months after we bought ours.
This photo is the new front cap design that came out on the later 2008 models. Notice how the edge of the front cap is cut in to prevent contact with your pickup. Having said that, you still won't be able to make a 90 degree turn.
Hope this helps you make a decision.
