For sure. If you can bust out another one at the same time, might as well
The horse stall mats did add some height, but I think it makes the side (top access) compartments more finished. I was admittedly rushing when I cut my side panels down, so my gaps aren't perfect, but with some good caulking it should clean up well. Also make sure to fully think out the mounting points, as my first ones interfered with the drop in tubs. Also, on the drop in tubs, I had to modify them to clear the wheel wells. Essentially cut a corner out, inverted it, and epoxied it back together.
