I've got the rubber floor in mine. going to have to patch a couple of rusted through places soon. the matting under the rubber is great for retaining water. be careful with that. but I like it better than carpet.
Finally got some 35's on the old girl! They are just some generic mud tires but much better then my old 33 AT's. So far I have been really happy with the JBG 5.5 inch lift kit, the only thing I would do differently is buy better shocks!
