Came back from a trip to Sportsman's Warehouse, and it turns out they have Scepter Military Water Cans (MWC) in any color you want, provided of course that color is Desert Sand. They had both the 5 gallon and 2.5 gallon, which is the first brick and mortar store that I've seen with them on the shelf. Prices weren't very good, but nice to know I can grab another one if I want.
$63.99 for the 5 gallon
$49.99 for the 2.5 gallon
