Hi i am a new member with a 2007 Ram 1500 2wd with the hemi. I have a 23' travel trailer and am wondering what the best tow speed is for optimal fuel economy? The truck will pull it 80MPH all day long but I know I am sucking fuel. Will slowing down help that much with a trailer? I know the trailer causes drag so what's everyones opinion? Thank you

 

ABSOLUTELY!! the more of a brick you are driving, the more critical speed is. optimal for fuel economy with a trailer is probably between 45-60, but then you'd be crawling.

 

The wind resistance is killing you. Just depends on how bored you wanna be at 60 mph.

 

meh the only way you can be difinitive about it is fill er up and go on a trip glin 80 there and 60 on the way back and see what the dif is in mpg's...my truck (04' 2500 4x4 Hemi QC) gets a good ole 8-9 mpg's when towing the dump trailer full about 9,000 pounds

 

My Ram (hemi) gets between 8-9 MPG pulling a 28' travel trailer. (5800 LBS)I try to keep it at 60-70 MPH.
But you guys are right, wind resistance is the killer.
