For those that responded that they use it at the campsite, thanks for the idea. I hadn't thought of that.
Also, for those worried about the bikes not being strapped down. I did strap the outside bikes to the bed rail and the inside bikes together. I used the plastic buckle straps which snap together quick. Not sure if it is needed, but it gives extra stability. In my test drive I drove pretty aggressive and they stayed in place.
Here are the pics I promised from the first trip with the rack. Not real easy to see the rack with the bikes on, but you get the idea. It worked great and was really stable. You can see the outside bikes strapped with the plastic buckle straps and the inside held with small bunges. I also cut some pool noodles to help secure the tires but it is not needed. Hope it helps.
