I know my truck has a bedcover. As for the air bubble effect I've seen many trucks with beer cans playing the Houdini flying up and down and around and around in the truck bed. They never seem to fly out, HAS TO be the air bubble theory.

Speaking of air bubbles, I ate mexican food for lunch, gotta go............

 

Thanks for the input everyone. I thought it sounded a little odd. What are these lightweight covers everyone keeps talking about? Anyone have any pictures??

 

Lightwieght = canvas
Heavy = hard

 

are these the retractable covers that you can pull over the top of the bed versus the hard fiberglass ones? I think everyone was saying a tonneau cover is what got me.

 

Here is the Undercover.

Hard molded plastic cover at only 58 lbs. It's a very popular cover up in the 2004-Present forum. It has been mentioned that one can walk on top of it without any trouble of it bowing.

You know I was just messin with you yesterday about the whole "air bubble" thing, right?

 

I know YOU were, hence the cartoon. Which, by the way, was genius.

 

Said cans do fly out at about 100 MPH...not that I would know this or anything...

Here's what I want to know: Does a toolbox like the one on my truck affect the "bubble" in a good or bad way?
