No surprises with this product. It's built well... maybe too well (it's heavy). Seems to me the tubing could be a lighter weight material for easier handling.
I mounted via T-Track mounts to RSI Smart Cap Load Bars and had just enough clearance to open the tailgate window. It's perfect. I did, however, need different mounting hardware (stainless M8x16+locknuts) as the T-Track hardware doesn't work with the Load Bar tracks.
Additionally, in order to fully install the included T-Track security caps, I needed to remove material from the the inside of the caps to provide enough clearance for the locknuts. I recommend installing the padding before mounting the unit on a vehicle.
