A lot!Thanks, I looked that up. I wonder how much it is reduced if someone goes to 60 sq ft frontal area?
I don't know all the math , but the fact is that flat frontal area is like pulling a parachute down the road and it is every bit as important as trailer weight.
Weight is most important for acceleration.
Aero is most important for maintaining speed.
So you can tolerate slower acceleration better than high cruising speed.
I tow a Scamp which is the best aerodynamic design in RV trailers.
My 2.5L TC , at rated towing weight limit in combo with my Scamp can achieve 25MPG at 60MPH.
18MPG at 65MPH (Average conditions)
I have a friend with a tall flat front 14ft cargo trailer... The TC would strain to tow it empty and not much more strain loaded.
Bottom line is that when towing... speed is most expensive, so keep the speed down and stay on the road longer between stops.
