Not that I work for RDC but, it's my guess this would be exempt because its a big heavy (48-50 pound box) and not a lighter package of t-shirts or some DVDs.
FWIW, I sell a lot of these and frequently share my vendor spot with their rep. To avoid costing racers/crews shipping charges you can order them from the shop and I will bring them to a race for you.
Ultimate Off-Road Jack
Also, they came out with a new jack. It got big ol wheels on it and rolls over uneven surfaces with ease.
And, NO those arent harbor freight lawnmower wheels. The wheels are made of some fancy composite stuff developed by dudes in lab coats. The wheels are stronger than the jack is actually. I've seen some first hand "go ahead and try and break it" efforts. These are tougher than hell. They make great jacks for pit stops.
Like the other version pro-eagle has, this one has a mount that not only holds the jack itself but the handle as well.
