Height in bed with factory tonneau cover?

Does anyone know what this measurement is? I don't have my truck yet, maybe two weeks to go, but I'm thinking about cargo management possibilities when camping. I'm wondering what the tallest box I will be able to slide out would be without lifting the cover. Thanks!

 

Here's all the measurements I took from my short bed when I was considering the same thing. With no bed mat, you can fit anything 18.5 inches or shorter under the OEM tonneau.

60" long
42.5" between wheel wells
35" long wheel wells
10" high wheel wells
52.5" wide in back
18.5" high

 

Thanks! Exactly what I needed. What solution did you come up with? I would love to have a bed slide but can't come close to justifying the cost.

 

I got 2 Sterilite 40-gallon Industrial totes (pics here) from Target for $20 each. They fit perfectly, but you still lose a lot of storage space just because it's harder to pack things around them. I took them on our first camping trip and had the bed completely stuffed (wife plus two kids along), on the second trip I left them home and bought 4 of these instead and we had tons more room:

I still kept the totes to store camping stuff in though, and this weekend I'm taking my daughter camping and bringing just one tote to throw our bags and pillows in to make sure they stay dry.

 

The totes look pretty good. I'll probably not be able to use the space in front of the wheel wells anyway because the bed rack with the RTT won't let me fold the tonneau back. Thanks again.

 

Ah, yeah if you're going with a RTT they'd be super nice with those handles, since you can pull them out easily. That's my dream someday...
