Doesn't look like it will be an issue based on those pics. Am I incorrect?
I sprayed a DIY bedliner called Raptor in there. I did a write-up on that too.
By default everything has a coat of paint. There is a small chance that water can seep under some sound/heat goop (that is painted) and start to rust were you cannot see. Its applied in the footwells and under the rear seat area. At least people have found rust there when removing it before bed lining. I wouldn't worry too much about that, but would try to remove any standing water.
