I knew right away it was a spreader, but what I actually saw in the background was that truck body with the twin propane/butane tanks, and figured what you needed was a spreader to handle them. I couldn't figure the little pipes on the ends of the vertical rods because I figured you'd use hooks, but then I figured you just used whatever you happened to have on the back of your truck.
But, when I saw how you actually used it, you were redeemed in my eyes - those chain guides were exactly what you wanted, not just what you happened to have!
Your heart musta gone up into your throat a little, when that top pipe started bending!
