I am posting a pic of the frame in construction. The watertank is BEHIND the axle, and straddles that rear cross bar. The tank is about 7" deep and is made of 3/8" welded poly. It has an 1/8" thick skid plate protecting it, and is vented above the frame rail on four sides. I used a marine potable water pump abut 1.5 GPM and 3/8" silicon tubing to plumb out the side of the Delta tongue box, which houses the batteries, pump, charger, etc.
PM me if you would like details.
