Does anyone have a range of MPG for a F-450 dragging a 18,000- 21,000 5er? is it much different from Ram 3500?

They are all so close that it just isn't a factor.

Thanks Scott, kind of figured that. Thinking about a 44 Santa Fe Mobile Suite or a 42RL Luxe and an f-450 instead of the ram.

It would take essentially as much fuel for each truck to do the same load. I would estimate 8-11 MPG depending on the depression of the foot pedal on the right.

The 450 will have a heavier curb weight before you hitch anything up to it , if the 3500 has the capacity for the trailer it may get a bit better mpg having a somewhat lighter curb weight I think you will find many 3500 models have larger or equal payload ratings than the 450 and probably better mpg when not towing or hauling, the 450 will have higher tow ratings if you need them . Either way the difference is minimal.

I have a 2017 F350, 6.7. My trailer is a 34’ keystone Laredo. 13k+ towing. My mileage varies mountains about 10, flat about 12. The wind also plays a big factor.

The gearing in the back end has a big impact on it too.

We have a pair of older Fords with the 7.3 mated to the 6 spd. standard, 1 is an F350, the other is an F550. Both have the same chip and air box setup, and have nearly the same mileage on them.

The 350 has 3.55’s in the rear end, the 550 has 5.13’s in the back. I don’t think I’d care to find out how fast I’d need to go to hit the governor in the 350, I know it’s at 70 mph in the 550, at that speed the 350 is just chugging along.

I suspect the Ram would have 3.73’s and the F450 would have 4.10’s, maybe even a higher ratio.

Why do you think you need a 450? If you are stuck on Ford a 17 or newer 350 will do just fine!

I tow as much or more than your rig will weigh with my RAM 3500 at 33k combined or 35 if double towing my Motor Cycle trailer with two Cruisers.

Pretty hard to beat a straight 6 for mileage.
