Losing items in the truck bed

I was just shocked at how the heavy stuff floated when the 5er was attached. It must be some weird aerodynamics. I remember my wife asking me what I was looking for...I told her the chock and she said it was right next to the bag of returnable bottles she put in. I said "what bag?"

I will take the trade off though. My 5er is heavier by a couple thousand pounds but I get at least 1 more MPG. Doesn't sound like much but when I was getting less than 8 before, it makes a difference.
