I HAD a good one till the other night when it flew off the truck that was on the rollback. The back glass was off, I had the truck on the rollback backwards, it caught all that wind trapped inside it, and broke thru 3 of the 4 bolts, and the 4th bolt damaged the hell out of my almost perfect bed and the cap flew off about 30ft in the air did a couple summersaults and landed in the middle of I 240. Luckily no other cars got hit, but came oh so close. It's now trash or I'da given it to you. I'm more upset about the bolt that bent over and pulled the bed flange over and out of the bed which wrinkled it all the way down to the top of the fender well. It sucked bad. I could give a rats ass about the cap, thankful noone was hurt, but am sick about the bed damage.
