The under bed tank became so hard to find we started making our own. A lot of people showed interest but we do not fabricate for any but our own projects so I did a write up on fabbing one up with home tooling. Not as pretty as the ones we do for shop customers with all our sheet metal equipment but it is cheap and out of sight anyway. Don't know on 1 Tons but on 1/2 and 3/4 the tank measures 13x13x21 inches. We use 18g cold rolled coated or 20g stainless which requires a TIG machine.
Common tools and using table edge to make bends:

All seams are welded and frame brackets are fabricated. (pics if interested).
