looks good to me. id probably prefer it with tonneau cover. im sure the topper will look fine, but im not sure how the 'walkthrough' is gonna work. are you going to connect the topper to the cabin portion so it looks like one piece? i would hope any vibrations or body flex wont crack the seal between the two.

nonetheless, looks good. i never liked the rear side windows on hardbodys. it would be pimp if u could weld in some metal and lower the window top to match the top of the window on the door.
