Truck bed width

I'm getting my truck next month, but am hoping someone can help me with this. Thanks.

 

Am also interested in this dimension

 

Lookin the owners manual, page 428!
There is a 6 degree angle, so the top of the board would be 62.2in and the bottom would be 60.7in.

 

Thanks Hike!

I read the manual the other night out of sheer excitement and anticipation (don't have my truck yet) must have missed it

 

I know the feeling...I pick up my truck this Wednesday and already read though the manual

 

Thanks. I’ll need to find the owners manual. I’ll likely add some weather stripping to each edge as well.

Edit: Here’s the info.
