How much difference in fuel MPG`S have you had with a bumper pull compared to the large wind resistance of a fiver?I have noticed a high fuel consumption in a head wind.Is it streamlining or lack there of that is to blame?Feel like I am pulling a 13 ft high box at times.I see trucks with all sorts of streamlining on the road.JUST CURIOUS-not that I want a travel trailer/bumper pull unit.

With my ram 3500 drw 4x4 I went from getting 11mpg towing a 26ft 5000lb TT, to getting 9mpg pullling a 40ft 14000lb fiver..... not enough difference to make me worry any.

Whatever part of the 5th wheel is above the truck acts like an air brake. Plus the extra weight.

Ana Awful lot depends on what your pulling with. 4.10 rear end Cummins dually pulling 13,500 pounds I can get 11.5 between LaPine and Lakeview. 9.5 between Salem and Bend.

Dont assume just because its taller a 5er has more air resistance than a TT. 5er and TV act like a single large mass cutting through the air while TT and TV act like two separate masses with a lot of dirty air in between.

I've pulled cargo trailers, travel trailers and fifth wheels. Sometimes the mileage is the same, sometimes it might vary by 2 mpg. Big deal.B.O.

I actually get better MPG towing my Columbus fiver than I did my 26' Jayco TT.
I'm sure aerodynamics plays the biggest part. Towing the Jayco TT was like pulling a big square box down the road. This is with my 6.7 CTD.
