Before I got a Truck Bed/Camper Top for my Pickup; I made a PVC rack like the one pictured prior, it worked without a problem, be sure to velcro the Wings and Fuselages securely in the Rack, and be sure that the Rack itself is fasened securely to the truck as well, I was fortunate because I had one of those Rack/Rail Tie Down system on the floor of the Truck Bed; drive a little slower, angle your rear view mirror down so you can observe your planes and wings while you are driving; and pray that it doesn't rain; I might add, that I now have a top for the Truck bed and I still use that PVC rack.
