Anyone installing the factory accessories themselves? Easy as pie or having a few problems? I haven't purchased many of them and probably will use after market for anything else. Full glass windshield was easy peasy but the wiper and washer not so much. The cab seal kit was just so so. The bottom of the passenger door seal won't stay on, not enough clearance. I'm kinda worried about how long some of the other pieces will last or stay on. I bought the cheap(??) tailgate and only one of the threaded rods will screw into the factory reciever! I haven't figured this out yet because the reciever screws into the place where the rear tie downs bolt in. These hold the gate in. I'm really pretty disappointed in Kawasaki!
