I took about a 4 hour drive today and I think I'm OK as far as the heat issue is concerned. I felt the cover during gas and food stops and could feel no increase in temp. There is a lot of room for air to move around under the truck. My theory is the box builds a small amount of air pressure inside which allows the hotter new air to push past.....of course I just made that crap up, so take it for what it's worth, LOL. I had this cover on for about 40K miles. Took a look at the odmeter today and just tipped over 47K. Dang they add up fast!
