Thanks guys! I backed in to the water and was going to hop out for a shot with the reflection. When I opened the door and realized how deep it was I hopped in to the back of the truck. I scooted over to the passenger rear corner and jumped to dry land. My wife drove it out after the shot...and gave me hell about stranding myself in the water.
I do have a full spray in liner in this truck. The inside of the bed was as slick and shiny as the outside before I had it installed but it was useless.
Depending on how bad your wavy floor is, a rubber mat could help disguise your problem. My liner has been useful, but they're not as great as they try to claim them to be.
