I'm starting the build based upon our existing 2003 tanker below, then I'll starting incorporating things from the new tanker over the next year as the manufacturer starts providing drawings and pictures.
So far, it's mostly a stock Globeliner chassis except for the longer frame rails.
I decided to keep the motor/transmission forward, so I made a longer drive shaft.
I plan to carry just under a gallon of water, which is about 8 lbs, so I need to stiffen up the rear suspension. Any suggestions on how to do that would be greatly appreciated - stiffer leaf springs, add a leaf, heavier springs in the shocks, etc.
