Leaked water into the cab.
"Leaked water into the cab. Went back and read the directions over and over we did not miss a step. Ended up having to get small rubber washers and also applied a clear sealer over top of the bolts and all the openings. You need to adjust the contour of the bottom to seal better with the cab. Everything looks good and works as it should, but very disappointed in all of the extra work we had to do to stop them from leaking water."
