This model does three things very well that address all my concerns: it stays balanced while rolling, it is much, much easier to loadandunload thanks to a zipper that goes all the way around the head of the clubs so it opens more like a book, and it has an awesome set of retractable legs that make it into a four wheeler.
Once sidled up to the building, a crew uses a scissor lift to unload giant enclosures made of Lexan and aluminum, dubbed Universal Load Devices (ULDs), which can weigh up to two tons each.
