    Around 2006 they moved the fuel tank back to the second bay to decrease the weight on the front axle. I can get 15 more gallons into mine by leaning to the right and filling on the left...the bottom of the fill tube is lower than the top of the tank. I’ve but 160 gallons in a 150 tank.
  • I don't use the small doors...just open the big ones and viola, there they are!...Dennis
  • Don't be embarrassed these machines are complicated and we are all learning

    On both sides you will find a small door approx. 6" sq .
    They both need a key to open .
    Inside those fuel doors the cap screws on and should be on a chain or cable .
    Many of us tilt the coach a little with our air leveling so we can fill the
    tank better .
    Don't try fill both side or have the opposite cap off you can have diesel
    running out on the ground .

    Our engines use the same oil as the big trucks 15/40 .
