REG cab owners: what do you do?

This questions for all the reg cab people put there. What do younuse/have to stop you stuff from sliding all over the place behind the seats? I need to come up with something quick, I just about smashed open a case of beer!

 

I took my stock rubber floor mats and put them back there. Works surprisingly well. I was going to use bungie nets, but haven't found need to yet.

I have the Husky X-act fit, or some such, for mats in the front now.

 

Found a plastic tray in the shop that is a close fit within the recessed area. It's temporary until I mount an ol left over good sized, stout, plastic, locking toolbox in there.
Try looking for sliders for a reg. cab.....it appears they don't exist.

 

Found this on TacomaWorld.com. Maybe doable on a Reg cab Tundra if you have an inventive mind and some spare time: https://www.tacomaworld.com/threads/diy-behind-the-seat-storage-bins-regular-cab-2nd-gen.285899/
