PDQ Tools sells this handy item. I often use my quick-stand while working hail on a SUV's or trucks. It's stable and offers a good sized platform to work from while not being too big and bulky. The unit folds up so transporting and storage is easily done. Unless your are 6 and a half feet tall, I highly recommend getting one before hail season is upon us. While not in use the platform also makes a great storage bench for your tool bag or anything you want to keep off the ground.
