Atlas O 20,900 GALLON TANKER

  Al,  to make it short....NO!    There are no 20,900 gallon tank cars out there.    A few of us on the forum here have talked to the guys at Scale Trains, about doing their beautiful oil can tanks (HO) in O scale, but I doubt very highly that it will ever come to fruit.   At Trainfest, you hear a lot of BS from various manufacturers about them wanting to get into O scale (2 rail now), but I think it is just to appease the person asking, and get them out of their hair!    One can always hope however for someone to finally step up to the plate...........
