85 PT40 fuel capacity

[mrkane1952]

Greetings:

The documentation states this bird has a 300 gallon diesel tank. Over
the last six months, I usually filled the tank at 1/4 remaining
indicated on the gauge, which was about 210 gals. Anyone have
suggestions about the actual capacity and the point when the generator
quits drawing fuel? Are these coaches enough alike for others'
experiences to apply?

(Fuel economy has been about 4.9 mpg over 10,000 or so freeway miles,
mostly towing a full-size pickup and running the generator.)

Thanks--
