One of the guys in our group got a new small PU and with the large planes he flys had a problem. But he got a neat "extender" that solved his problem. I don't know where he got it or what it's called or who makes it, when I talk to him I will find out, but maybe some of you will know and if so let us know. Anyway, it is made of round aluminum tubing, nice and shiny too. It has three parallel bars on some vertical pieces and it's high as the bed's height. He lowers the tailgate, and hooks it to the truck's tailgate latches, and it sits down on top of the tailgate, and looks like a heavy chrome fence back there. It locks on solid and nothing can get out, unless maybe a screwdriver or a small tool, but a box, plane or wing, no way. Looks good too. Check with your local PU accessory shop, they probably handle them. I bought a "previously owned" long wheel base truck because of the price, and glad I did. My planes got larger too!
