My approach would be to investigate the cause of the leaks first. It might be a fitting, or drain port.
Depending on the material used, sometimes repairs can be made to the tanks. Plastic can be welded with the right equipment, and fiberglass is also repairable. I imagine that Airstream could supply new tanks, if no other of the shelf tank fits.
A good source for generic tanks is Ronco Plastics, or Plastic Mart
