I use a system the same as Safebet. I designed it to carry 4 planes. The only difference is that mine has PCV tubes that rotate over the top and latch on the opposite side. I place the unit in the back of my pick-up and then load the planes in there respective slots. Ithen use a cargo net over the top. I also use a cargo rachet strap around the legs but I really don't think it is nessary but I use it anyway. Wish I had a canopy or a trailer but have a wife and kids instead.
