Try the Performance Xport "Flatbed". I have the 2 bike model. The insertion tube is up swept,collapses for access to tailgates and it fits both 1 & 1/4 and 2" receiver's. Tried the Swagman and Yakima tray style receiver rack's and,while both solid products, they come strait out of the receiver hole and I was bottoming out all the time. This would be especially true for the 4 bike model.The only thing to watch out for is making sure you have the center support locked before you take off or you'll end up with bent wheel's as well as dragging you're bike down the street!
