Just added two of these to my truck last night. The best price I found was at autoplicity, for $157. Installed very easy. Only two problems to note. They are lockable, and you would think that if you buy two of them, Autoplicity would make sure they have the same keys. Not the case. The second is that the bracket arm is shipped stored inside the case, and somewhere along the way it got bent. It was easy enough to straighten it back out. So far I really like them. Only wish they were even bigger. I have some heavy duty jumper cables, and in one box I was able to store the cables, a compressor, a portable tool box, and a 4 way lug wrench, and still have the two trays empty.
P.S. Just called Undercover. They will sell me a set of two replacement locks for $26. Since I have a cap that locks, I don't think I will end up even locking these boxes most of the time, but it's nice to know that I do have an option in case I change my mind in the future.
