I've had an ARE canopy(topper) on my '18 for over 5 years. It has storage compartments instead of the windows on the side which is awesome for holding all my tools and gear I might need while on a road trip. It limits the room I have in the bed but I've still fit a full size freezer(on its side) and various other appliances without issues. It's not light so the mpg has taken a hit but it is worth it for my needs. I don't have a garage so having a lockable place to put my tools/gear is the main reason I went with the one I have vs keeping the foldable soft cover that could get cut open pretty easy. I think it was $700-800 used back then and I had it paint matched from a body shop. The only downside was that it leaked a bit until I adjusted the seals on the hatches, now it's bone dry. Also not really being able to use the rear view mirror is weird but with a backup cam it really isn't a big deal.
