Deep Boot Tray vs Regular Cargo Mat
I use a blanket over the rear bumper when loading a bike. The Mercedes rear bumper fold-down protector would be a good item to have.
One thing to note on the deep tray, is the raised edge gets flattened when large items (boxes, etc.) are loaded. Not a problem, just something for awareness. It also makes sliding large items in and out require a little more effort. Not a deal breaker for me.
The raised edge is nice to prevent round items from rolling off the tailgate, and also acts as a water trap for dripping water, melting snow, etc.
