Help selecting Pelican Case

Hey guys, I'm about to pull the trigger on a pelican case but wanted to know from anyone with more experience than me, what would be the ideal (largest) model for my DCSB that will sit flush under the tonneau cover??? Any help would be greatly appreciated!!!

 

Why are you going with a Pelican? If it's because of there waterproof claims my piece of advice for you would be RUN AWAY. If you're looking for a hard plastic case with foam inserts to store fragile gear there are many other vendors than Pelican with much better price points.

I do like that Pelican claims that anything you put in their case which does become damaged due to water getting in is 100% covered.

I use them on commercial raft trips where they're in a whitewater raft getting splashed and they've always always always let water leak in.
