Thought I would share the final product I have been tinkering with for a while. I wanted an easier way to transport the 12x20, 4 holders, and my Gitzo with one cart holding everything. I started with an old Samsonite that is 30" in length. Then went and bought 2 tube tires at Northern Supply that are each good to 150 lbs. Called my good friend Mike who is a genius at design and fabrication with all things of metal and steel. After giving him the idea he went to work cutting and building steel square tubing, angle iron supports for the 1/2" axle and we ended up with this great carryall for all the gear. It rolls like a dream, has a pivoting arm that swings out to put it down at a 45 degree angle, and holds everything plus some. My Big Bend trips are about to become a pleasure. If anyone has questions e-mail me and I will be happy to answer any and all.
