Up until a few weeks ago when I finally purchased a trailer, I hauled my planes in the bed of my truck without a cover. I built racks out of PVC and pipe insulation then bungy cord them into the bed of the truck. When hooking up the bungy cords get them slightly snug, but dont pull them to tight or you can break the pvc or the plane. Here are some pics from another thread on this same subject. These are not my photos, but I modeled my racks after the ones shown here. They work great. The only thing they cant help with is those days that the rain runs you off from the field. It is no fun watching everyone else leave while you are sitting under the shelter waiting for the rain to stop.
