I would not haul 115 gallons of fuel around all the time to prevent condensation. I have used a 60 gallon RDS tool/box comb. for 5 years and never had any issues with water or condensation, whether full or empty for months at a time.

After many years of using extra fuel tanks, and storing fuel on the farm. Definitely keep tank full to prevent condensation. Add a good diesel fuel additive, and this will also help keep if fresh. The only time I've had diesel go bad, was after about 2 years. It did go bad.
I'm using additive all the time now for extra lubrication, extra cetane, and help prevent water.
