Just looking to see if anyone has made their own rear cargo box and any ideas how to mount them?

I’ve made my own bracket to mount my outboard on my rear rack and just used a bolt that goes through the top and welded a nut to a plate that goes on the underside of the rack. Only thing is that the outboard is exposed to the dirt and branches, a blanket covers it but it’s a little bulky. I’ll be making some sort of rear cargo box so I can lay the motor down and have a lid on it.
