Rockwood/Flagstaff - travel with full fresh water tank?

My water tank is over 100 gallons and would weigh over 800 #. Factory has it held with 2 straps held in place by sheet metal screws to the frame. It will take very little time and effort to put in more substantial bracing.

Before I would travel with very little water and that was not a issue but now I plan on longer trips to remote areas where I want my own water.

I know I don't want to deal with replacing the water tank on a long trip at my expense, (out of warranty).
