That is the same bed extender I have except it says AMP...now I know what I am going to do when I get some free time.Here you go. I have this on my 2013 and it’s come in handy many times.

I can't say enough good things about a bed extender. I use mine so much we have decided we have to get an 8 foot bed. And the bed extender will be installed and I am sure we will still find a reason to use it.
