I average about 10 mpg on a 400 mile trip. Almost all highway travel at 70 mph. Passing slow traffic is almost as easy as if the truck wasn't loaded. (except for the 26' total length and 8' width)

So many variables to consider. We are around 21K truck and 5th wheel. we have seen 6MPG we have seen 11 mpg. 8 to 8.5 is a good average. We are hooking up now for a @100 miles trip Westbound on the Ohio TPK. It is in the mid 80's low humidity, no wind. We have done this trip before and I would expect to see @ 9 maybe 9.5MPG. fairly level road at the speed limit. MPG is a fleeting figure..

Our latest towing mileage after slowing down to 55 & 58 form 60 & 65 was 8.92 over 10700 mile trip (Alaska and Canada). Before it was in the low 8s.

2006 F250 SD Super Cab 2wd, 6.8L V10, 4.10 diff, 30 foot fifth-wheel trailer, combined weight on scales is ~16,000 pounds. 9.5 mpg on mix of flat ground and 6% grades.

 

2000 F350, V10, 4.30. I have slowed down to 55 and 58. I came back from Colorado through southern NM mountains (Ruidoso) and the worst tank was 7.85 into a howling wind. The best was 9.25. I averaged a bit over 8.3 and my CAT scale ticket says 21345 total for a 36 ft. fifth wheel and I did have to go to 4,000 rpms on a few hills and passes.

 

2008 F350 cc longbed 4:30 gears, 275-65-20 tires. Currently there is 15,550 miles on the truck.and I have added a Magnaflow single in dual out muffler. Truck weight 9520lbs., trailer 2003 Sunline 267SR weighs in at 7200-7500 depending on how much stuff wife brings, total weight of 17,020 lbs. I like to keep up with traffic so my gas mileage might be worse than some with similar weight, but I average between 8 and 8.5.

We tow a lot of different trailers, that trip was the worst, on a trip from GA to CO. It was actually worse still crossing Kansas with a viscous head/cross wind. In fact, that day I passed another Excursion towing a large travel trailer. It seemed like he had all he could do to hang onto it.
