Fuel tank capacity on 2000 Chieftain

[Matt-n-Dede]

I have a 2000 Chieftain 36L DP.
On all the paperwork I can find it is supposed to have a 90 fuel capacity. The gas versions have a 75 gallon capacity.
This past week, I ran it to empty on the gauge and I could only get 65 gallons in which took the gauge to full.
I am trying to find out if this is unique to my coach or do other owners have the same issue and therefore the books are incorrect.

Thanks for your replies....

You have a 90 gallon tank.

It's not uncommon for the gauge to inaccurate.

90gal X 7mpg = 630 miles
90gal X 8mpg = 720 miles

I would not run over 600 miles on a tank of fuel until I had a handle on my mpg.

Thanks Tom for your reply.

This last tank got 592 miles and took about 65 gallons to fill which is about 9.1 MPG. This was pulling a Jeep Grand Cherokee and a lot of wind, mostly from the side.
This MH is hard to fill up because of spitting back but I filled as usual and the gauge showed full. On my previous fillup, I had less than a quarter of a tank and the numbers line up the same.
I normally like to fill up before it hits a quarter of a tank and I do not have much range right now.

Would definitely like to hear from other owners of their experience with this unit before taking it to the dealer.

Matt, that sounds like your vent tube is plugged.
