I have used it 4-5 times so far but have not yet gotten to 5 bikes.  It will be tight with 5 bikes but I have no doubt it will hold them all.  It is a solid rack.  Quick and easy to attach to my truck.  I used to dread going biking because of the hassle of mounting my old roof racks or taking the cover off my truck and finding a way to secure the bikes in the bed.  Now I look forward to opportunities to use this rack.  My only reservation is it make me a little nervous with the bikes where the cables run under the top frame bar to be basically secured by them.  There are groves which are nice but I wonder for the long term health of my cables to be slightly pushed one way or the other to fit into the groves.  I might end up with another Swagman bar adapter for my bike to avoid this issue.  Those adapters are quick and easy to use (I needed one for my son's oversized frame).  So in summary, if you need to carry 5 bikes this rack is perfect, if you only need 4 I would go with the Swagman XTC-4 Cross-Country.
