Excellent
It is everything they advertised it to be. It is well made, came with everything I needed to install it, it was easy to install. I don't like the tie downs to hold the ladder in place when not in use. They are in the way when sliding stuff in and out of the box - so if someone has figured out a better system I would like to hear about it. Otherwise it is great.
