Fuel tank capacity Monaco Cayman 2003 Diesel

I would like to know how much fuel you put in your fuel tank? The book says 75 gallons. The other day, it was between empty and 1/8 and I added only 53 gallons. So this would be 22 gallons left to use, quite a good leg of travel. I am scared to take it down to Empty.

Please post in other thread duplicate thread.

    The fuel sender on Roadmaster chassis can be calibrated by set pot screws on top of the sending unit. Roadmaster chassis have access to the top of the Diesel fuel tanks unlike Frtline and Spartan. You fill the tank up and then adjust the set screw in small increments until the gauge needle is on the full line. It can take up to 30 minutes to do this as the gauge needle takes time to respond when adjusting the set screw. Doug

    I have a diplomat with 100 gallon tank, the most I've ever put in was 75 gallons and I wouldn't take it any lower. No need to risk running out of fuel. I know my mpg so I fill around 500 miles
