Simple mod for crew cabs: plywood deck over folded seats

I did something similar long ago, but mainly with the idea of protecting the back seats from the dogs. I used blue foam sheet on top of the plywood to give them some traction. However we now have a topper on back since we switched from fiver to TT and I plan to relocate the mutts to that. I need to make some alterations to the topper first before putting the plan in action. The wife of course has low enthusiasm for the mutt relocation plan. I'll keep your idea for the seats in mind tho.
