Here are some pics of the Tanker truck I have. It's a 1954 GMC Texaco tanker truck 302 cu. in. 5 spd. 2 spd auxiliary transmission. It was originally a hydromatic and I think that's why it has the reduction transmission behind the main transmission. It's a really solid truck,5 window cab, runs decent could use a carb rebuild. Definitely a good project. I have never seen another tanker quite like this one, the fuel delivery is on either side of the truck and the rear has a cargo area where most tankers deliver out the rear.
