There is that little thing supported by The Supreme Court described as "non-commercial personal
fair use act ".
If something is reproduced for personal and private use at home, its really hard to prove an infringement claim. If he ever decided to get rid of the cooler or move it to a public place, legally he would have to pull the graphics off the cooler.
One problem with the Fair Use Act is thats its gray as hell and is decided by a judge most of the time.
If he made a Red Bull decal and put it on the back of his truck, thats 100% infringement. But to make a decal and put it inside his house, not so much... still gray as hell though....
Anyway, back to the cooler, I like it.
