I have seen early Powerstrokes (2wd E4OD) get 23 highway running empty. Because of the fundamentally different way diesels work vs gassers, mileage will vary more due to speed and load. That 23mpg truck drops down to 12 towing his trailer. Also, gearing is more important with diesels. 4.10's are really going to cost you if you like to cruise above 65.
You will get stunning gas mileage!
Put a five gallon can of gas in the bed of the truck and it will last 500k!
Now, diesel fuel mileage may be a little different.
My 3/4 ton ext cab short be 4wd regularly hvers at 18 or so around town and I have hit 22-23 on the highway with light loads and keeping the speed down to 60-65.
But 20 on the highway at 70+ is pretty common for me.
Pulling the camper, again depending on speed, I have done as well as 15-16 mpg of fuel.
The bottom line: PSD's have great fuel economy potential; your right foot is probably the greatest variable in the equation.
