Bought a Bakflip MX4 for my 2023 Maverick - GREAT PRODUCT, GREAT QUALITY. The install was pretty straight forward. Only suggestion - place bed weather stripping (provided) on the front
bed edge (behind the back window) on the REAR EDGE of the flat surface. I placed mine in the middle and had to pull it up and reposition it on the rear edge because the cover did not completely cover it when positioned - a few installation steps later. Cover looks great and would definitely recommend !

Looks good, fits well, works great

Its exactly what I'd hope it would be! There were some rubber bumpers (1.5") that didn't stick well and when I called they sent me 4 new ones (I only needed 2). Now everything is perfect. Thx

Good Fit, easy install.

Very pleased with the BAKFlip MX4. Have only had it installed for a week, but it works well and provides good solid coverage.
