Diesel Question for truck campers

Depending upon the terrain and the amount of wind blowing my MPG with the diesel engine varies from 9.5 to 13.5 MPG. I have to plan on 9.5 MPG as we go where AAA does not, nor is there cell phone reception much of the time.

I am planning a trip to Glacier NP via eastern CA, eastern OR, Idaho, and western Montana. These areas have few people, few towns, and few gas stations, much less gas stations with diesel. It stands to reason that when you are in states where the total population is much less than for many cities San Jose, Seattle, Chicago, Atlanta, Dallas, Boston, Phoenix) that there will be fewer gas stations that can sell enough fuel to stay in business.

It is different on major interstates that support the trucking industry. If you don't mind doing all your traveling on the interstates and only going where they go then it is true that one can find diesel. But that is one heck of a limitation in the western states.

I have a diesel truck now but my next truck will definitely have a gas engine (and 4.10 gears).
