used for a side tank for horn and tire inflation. due to space constraints a bracket with small drain on top leaving an unused 3/8 drain plug, the bracket could be mounted a little lower on the tank like my parking spot! The brake cable barely comes out of the brackets that attach the tank to the chassis and if I had adjusted it lower it wouldn't have enough meat for the mounting holes at the bottom. Okay, I installed it upside down for future reference. Its light is enough for 1 person to position it easily.
