Storage under tonneau cover?

What is everybody doing for storage under a tonneau cover? My tonneau cover is a hard cover that folds back but does not fold all the way to expose the forward section of the bed.

 

Have you thought about a swingcase?

Swingcase on both sides here. Easy install and storage thats out of the way so you can use your bed.

 

Full set of Swing cases here. I found mine on CL for $50 for the set and I couldn't pass that up. There are cheaper brands that are available but I have no idea on the reliability of them.

 

build drawer or buy bed slider

 

I have a load bar across the rear of the bed. And a crate between it and the tailgate.

Curious, to those with swing cases, do they interfer with the bed ligths (if you have them)?

 

I have DIY bed lights.

 

A Plano storage container with a load lock positioned behind it to keep it near the tailgate.

 

My trifold isn't as water tight as I was hoping; some significant drips are coming in the back corners in moderate to hard rain.
Are those Swingcases water tight? Looks like an interesting solution for organizing some smaller crap I would like to keep back there all the time in a space efficient and hopefully fully water tight way?
