It has the dual 50-gallon tanks, nice.
I'm sure you know this already but for any novices out there, but if your run bobtail, these trucks not only have an inhumanly harsh ride, the brakes are also an invitation to disaster since basically all the weight is pretty high above the front axle so the rears will easily lock up and loose traction. They did eventually get ABS for the back which helped some. I'm not sure what year that was but my 1991 F700 doesn't have it.
Keeping the tanks full when running empty should help a bit.
Of course, it's more fun to run with a load anyway.
