Especially if the soil is loose, all that bouncing around in the uhaul would have broken a good portion of the root hairs, the tiny roots that do the job of water and nutrient absorption. Add to that the probable high temps inside the truck box, and you have a recipe for major plant shock. Of course, anything that is brown will never turn green again, but the best thing you can do is put them in the shade, out of wind, and water as needed. They will have to come out of it on their own, and don't expect them to look very presentable anymore, even when they are healthy and back to normalcy.
