Curious about the side mounting as well. Kinda doubt anything of substantial weight can be mounted. I just put my rack with extra crossbar on day before yesterday and am on the road the next couple of days. I’ll be mounting a Plano case, traction boards, maybe hi-lift in the coming days. 3/4” carriage bolts drop in and fit perfectly in the rails. I’ll be using varying length bolts, washers and nuts to mount stuff.
