. . .what is realistic mileage that you are getting with your setup. Please post mpg, speed that you are traveling to achieve this, truck brand, size, engine, etc and what camper.
To your question: 8 to 12 MPG
And that can be for diesel or gas - depending on who you talk to.
Obtaining a fair assessment on MPG that would be meaningful would have to be restricted to dually trucks if that is what you plan to purchase.
And it would realistically need to include a great many miles over many topographical features, wind conditions and driving styles.
