this is my first truck with plastic on the bed rails and tailgate. will their be any problems with the painted area its riding on over the years?

 

i was worried about the same thing and did what i think will prevent that. You can see the pictures in the "spray on bedliner" post
I don't think that many 09's have enough age to show signs of rust yet

 

I also was worried about that, plus how slippey everything was I put in the bed, so I told my dealer they could have the plastic liner to put in one of there other trucks on the lot and I ordered the dodge rubber mat for the bed and tailgate and nothing moves around on that mat

 

thebedrug is nice for that, nothing moves at all, I put wheel chair parts for it, batteries wheels all apart and it stays even when I get a bit jumpy on the gas. and it is comfortable to lay on if you want a nap under a tree, plus it doesn't wear at your paint since it is velcroed in. Looks pretty too, gas, oil, acid proof. pressure wash it off
