Ford 7.3 gas burner mpg hauling TC

Fast Lane Trucks has a 7.3 with a popup camper and they have a few youtubes where they discuss it including mileage. Check those out. I don’t remember the mileage they said they got.

I haven't see anything with a truck camper loaded up but,hauling a 12.5 trailer it averaged 8.4 mpg and empty 14.5 mpg..Of Course rear gear ratio's can change that alittle one way or the other..

IMHO,the new 7.3 isn't getting much better(if any) mileage than the old 7.5(460) ..But there was a good HP and TQ gain over the stock 460.

No one can possibly answer this. There are just too many factors:
highway vs mixed or city driving
speed
driver technique
wind
hills/mountains

This is very true...I get very good mileage with my 460 but others don't..I rarely put the pedal to the metal and keep it at or under 2k RPMs and have got between 10 and 14 mpg..

The op with his comparable TC to mine,would probably get about the same or better with the new 7.3, if he kept his foot out of it and kept it at or below 60 mph..Travel freeway speeds and the mileage goes South with big bore gas engines..

Easy to answer if you check your mileage while towing/hauling and take an average.

The biggest factor is always speed, so giving mpg value without speed is garbage IMHO.
On several big vehicles I noticed higher mpg in the mountains, than on flat freeways. That made me scratching my head for a while, till I concluded that in the mountains I drop the speed by 20mph, what gives me ca 30% better mpg.
So even when grades will eat 15%, my fuel consumption is still lower.

Btw, they changed the suspension and tires as well.

How does the camper affect fuel economy?

After the camper went in, we had to see just how much the install affected fuel economy. While the stock truck managed about 15.5 mpg and the off-road modifications changed that figure to 13.3 mpg. Over 964 miles, Andre used 84.424 gallons of fuel, amounting to a new fuel economy figure of 11.4 mpg.

Overall, the modifications we’ve made to the truck to date resulted in a 26 percent drop in fuel economy. When it comes to actually taking the truck off-road, though, the changes should make the Super Tremor a worthy companion when we leave the payment. That’s coming up in new episodes of our “No Pavement Needed” series, so stay tuned to TFLtruck.com for more updates on that!

The 460 ended production in 1997 from what I’ve found. Of course, the trucks are remarkably different than they were in 97. Better is a matter of opinion but dramatically different. The 97 was probably about 2000 lbs lighter and of course, the transmission is dramatically stronger now.

I’ll agree with other posters that mpg is fully dependent on speed and type terrain you are driving over. I’d also through wind into the equation.

That might be included in speed part, but I still remember moving with 7k cargo trailer from San Francisco area to Las Vegas.
3 trips, so average -going down to Vegas with ca 7000lb of stuff I was averaging 11 mpg.
Going back empty, I averaged 9 mpg. CC always set firmly at 60 mph.
You can figure out how desert winds can play with fuel economy.
