Pulling a trailer... I'd say carry a spare 5 gallons of fuel to be safe. Fixed. On a serious note, single digits definitely. Have you ever pulled anything with the truck before? How a truck runs unloaded can be a huge difference from when it's loaded.

No I haven't pulled anything this heavy. Only a 5x8 landscape trailer.
I had initially calculated 6mpg. But that means I'll need $300 to get there.
But I do believe it gets better gas mileage than I initially thought. With the gas gauge broken, and speedo broken, I pumped 16 gallons to go roughly 70 miles (figuring on 6 mpg). But I made it there, and back, and did a tremendous amount of driving before pumping gas again. I pumped according to 6mpg, and drove. When I pulled the fuel level sending unit out to swap it, I though my tank was empty. I was afraid to run it for fear of running out. But to my surprise, it was half full. Unloaded, the truck seems to get about 11-12. I'm going to fill up a gas can. Drive the truck until empty, and fill from the gas can. Then run it dry again.
Or possibly filling up, then driving for a distance, and pumping at the same pump. Hopefully it clicks off at the same point both times.

Keep in mind the speed you drive is going to have a huge affect. Your truck at 55 versus your truck at 75 is a huge difference. If you kept it at 55 I bet you can get the 10mpg. At 75, no way!

-Jon Try inputting your trips and fuel ups on fuelly.com to get a real world estimate of how your truck is performing. I did this with my daily driver and found out that my MPG gauge projects my car gets 1 mpg more than what I'm filling at the pump. I'm assuming your odometer is working.

My 77 w300 with 360 gets 8 empty. Runs out of rpm by 60 MPH.
I think you're initial estimate was righjht on the money for pulling a trailer.
Make your friend pay for the gas.

Pulling a 20' enclosed? I'd calculate at 6mpg and be happy if you exceed that. I think 8 is realistic, 10 is pushing it IMO. This one! I've had a few big block Dodge trucks. 7-8 mpg if your working them (which pulling an enclosed trailer will be doing), and hope for a tail wind! If your pulling a loaded box, that's taller & wider then the truck, into the wind, its going to suck down even more gas. If your tires are sun checked, I suggest you change them before you leave! Trying to buy Dodge 16.5 tires on the road won't be any fun. Driving 600+ miles on sun checked tires is asking for trouble. Sun checked tires around town might work out OK, but for hours at a time on the highway? No way! Just my opinion. Been there, done that. Gene

So you averaged 10.8 mpg. Not bad. I agree, that's good. My D100 2wd 400/4speed gets 9 mpg unloaded.
