2400 mile trip pulling 19,000 lbs

[WYCO]

We just made it back from a Glamis sand dune trip by Yuma AZ. The round trip from Wyoming was 2400 miles truck was awesome!! I averaged from 8.5-10 mpg pulling at 80 mph the whole trip hand calculated. The trailer is a converted gooseneck race trailer 42 long, 8 wide, 10 ft tall, slideout, triple 7000 lb axel 19,000 lbs loaded. Going over Raton pass truck did 55 mph, coming down had to help it with a few taps on the brake controller. In comparison 08 6.4 avg was 6.5-8mpg (without dpf), 04 6.0 was 7-9 mpg, 02 7.3 was 7-9.5 mpg pulling the same trailer. I am sure if I traveled at 62-65 mph I would have seen 12 mpg. This was by far the most stable pickup I have ever pulled with, even with some side winds at 50+ mph. Oh and only 1 regen that I saw, but thats prob due to running hard

Man thats nice mileage for that amount of weight. Especially with the DPF installed.

What is your axle ratio on the 350? 19k low profile is a lot easier pull than a high profile 5er camper, but sure sounds good.

My 2011 450 with 4.30's at 65 mph beats my 08 w 4.30's mileage by 20% (14.25 vs 12 at best hand calc) if empty, but when hauling 16k high profile at 65 mph I am lucky to gain 10%.

Thanks for taking the time to report how it did!

19k pounds is some serious weight!

Truck has 3.73 gears. Trailer pulls great for what it weighs, its a full 8' high inside but only 1.5' off the ground with a flat roof line. My old toy hauler a few years ago had more room over the gooseneck but pulled like hell for a 10,000 lb trailer.

Here is a pic with the 08 I had.

Awesome mileage!

I'm actually thinkin of getting a 6.7!

What is a DPF? I have a 2000 F250 7.3, I love it but would love to get a new one, but have been reluctant to pay 50K on something new.

Those are some pretty good numbers. Thanks for reporting.

That mileage is pretty impressive as I cannot wait to haul my tow hauler. The last couple of years with my 7.3 traveling from Michigan to Bristol Tenn. I averaged about 11mpg pulling a 42 ft. triple axle toy hauler weighing 16k loaded. The 4 speed auto has too wide of a ratio band and I'm hopping the new 6.7 with the 6 speed trans makes me proud..

That is some damn good mileage.

For comparison, just pulled our new TT (34' & 8,000 lbs) some 200 miles down to Port A from Seguin. Got 10 mpg. On the way back from Port A to Austin, some 275 miles, got 11 mpg. Both ways was traveling 65 - 70 mph.

I think the MT's hurt (weight and resistance) and I think the grill guard actually hurts the aerodynamics of the truck at higher speeds.
