For those of you who have asked about the hidden water tank, here goes. It is tucked up on top of the middle divider. Water tank is 8" x 8" x 3/16" aluminum beam. We tigged plates on the ends. We also put a 3/4" female coupling on the top and bottom for fill spout and drain spout. It was directly welded to the inside of the top of the frame. It gets it out of the way, as well as really braces it up nicely
Shot from just behind cab on the driver's side,looking towards the passenger's side rear.
This is just a few inches down looking from the side of box. Notice the orange cap to fill the tank.
This is with the trap door open on the top platform exposing the fill cap. It is a breathable cap so that when dispencing water, it won't glug out.
Being right handed, I wanted to be able to get to the water spout with my right hand. Therefore, it is just behind the storage compartment on the passanger side of the dog box. To access, I just open the door to that side. I did not want it out the back, as I viewed it as a potential knee-knocker.
Most likely, I will put a male quick disconnect fitting on the valve. I will then have the female quick disconnect with a short piece of hose, so that I can use it to rinse hands and such. If I'm just filling dog bowls, I will just let it pour straight down.
