Padipro:IMO an aluminum tank is the only way to go and a sling strap is very easy to make with nothing more then a large hose clamp, a couple of bolt snaps and a length of 1/4 inch thick nylon rope.

I did something similar for my pony. I went to the local hardware store and bought a dog leash. It was 3/4 flat webbing with a SS boltsnap on one end already. I bought another snap (with a "D" ring on the base; works great with flat webbing) and 2 SS hose clamps. Works great, looks "store bought", and was cheap. Couldn't ask for more!
