I am so sorry I took so long to get back. I did not realize that you had sent this. I already sold the Roll N Lock and have my new cap on.
I am in the Bergen county area, Elmwood Park.
Yes it would have worked with a bedliner under rail type.
Good hunting for a new top. I still reccommend the RNL.
I'm in North Jersey as well, and was wondering if you still have your Roll N Lock cover available. Also is it compatible with an aftermarket bedliner? I currently have a tonneau cover which I'm looking to replace and I have several holes cut out in the bedliner in order for proper installation. Thanks in advance.
