Driver's side box does NOT fit F-350 with in bed trailer plug
I purchased boxes for both passenger and driver's side. Tail light had to be removed on my truck to install bottom bolt, not hard, but they don't tell you to do this first so that the remaining holes line up properly. Also, my 2013 F350 with factory installed in bed trailer plug BLOCKS the locking of the box on that side, so now I either have to return box or spend $150 to relocate plug. Also, VERY easy to pop the heads off the supplied self tapping screws, and when they do, you're screwed.
