I bought a cheap hand truck from the local borg and modified it to
hold my cylinders, hoses, torch, etc.

The first thing I did was figure out the footprint of my 2 cylinders.
I flipped the hand truck over and welded (using my gas rig of course)
some angle iron to the bottom such that one leg or the angle was
flat against the bottom of the truck and one leg pointed up with
the truck in the normal position. This made a tray of sorts to capture
the bottom end of the cylinders so they couldn't come off the truck.

I was lazy and just looped some chain around the truck/cylinders 1/2
of the way up the cylinders to secure them.

I bent some 3/16" mild rod into a 2 gentle hook shapes and welded
one on the top & bottom of a side support of the hand truck.
The hoses get looped around here and the torch just hangs.

Finally, for tool storage, I welded an angle iron support to the
back of the truck to support a little, red toolbox. I can store all
of my tips, cutting attachment, striker, etc. on-board now.
