Sorry Xist. I meant between a tonneau cover and the LEER topper I have. The topper is basically level with the roof of the cab, and the corroplast bed cover was level with the bed rails. Didn't seem to make much aero difference. Now weight difference, certainly. It was obvious when going up hills. I'd try some A-B-A testing, but with my knee that's probably not a good idea. Besides, I have to have help to get the topper on and off the saw horses I made for it...
