4th Gen Cap on a 5th Gen?

Trying to find a cheap cap/topper option for fishing and hunting trips. Used 4th gen caps are easy to find... but would they work on a 5th Gen?

Someone mentioned here a while back that the 4th gens beds are totally square, whereas our 5th gens have a radius on the front side facing the rear window. It may fit, but not that well...
Perhaps someone else that has tried this can chime in.

Thanks,
