Bike rack is simple to assemble and Install,but your information about the installation does not say it bolts to the receiver with a metric thread bolt .That only matters if you also get the cable lock that comes with a 1/2-13 american standard bolt. I'm using on the back of a 5th whl RV.
Missing pieces and unsecure
This rack was delivered missing pieces (safety pin and cable lock). Bikes are not secure and anyone with an Allen wrench can steal it by just unbolting the bike tray from the hitch mount; these are the same bolts that were loose and one was missing from vehicle vibration within the first week. I guess I'm lucky I didn't lose a bike while driving down the road. I used loctite and a long cable bike lock to secure the bikes to the truck frame. Missing pieces are being shipped by Yakima.
Good quality and rugged construction!
This is a really nice bike rack but unlike I was told by the staff (Eli R) at "Auto anything" I can't open the rear door of my wrangler. I had the option to return the rack but time does't allow it and paying return shipping and 15% restocking is counterproductive! I won't do business with these people again!
