I wish I could get these guys to make a form fitted set for our EB. I used one of these systems in the back of my 06 F150 for work and camping. It was perfect. Was easy to vacuum or wash to clean, the padding in the bed floor was thick and I used it to sleep on when I went camping. even battery acid wont damage the material. I know I hauled greasy cylinder heads and similar in the back and it all cleaned up.
