After adding several units recently to the site and finding both US Tank and US Tanker on various nameplates, a call was placed to the manufacturer to determine the story. So, for those interested in the difference, the company, which is now called US Tanker, says that between the years of 1989 through 1996 they went by the name US Tank. Since then, they are known as US Tanker. The confusion was renewed recently with Tanker 72 in Woodstock which was manufactured in 1993 and is branded with the name of US Tank. (although it is currently labeled incorrectly on the site as US Tanker and will be updated.)
