Are there any mods worth while that will make the travel trailer or even an enclosed cargo trailer more aerodynamic? I've got a 23' Aljo lite. Wondering if a nose cone or truck top wing would be advisable?Also I'm looking into a enclosed cargo trailer for work. I tow about 15k miles a year for work. Wondering if there is an increase in fuel economy to be achieved with a vee nose rather than a flat nose trailer?

Anything to make the wind/air go around/over, not thru, will help. Better MPG through aerodynamics.

Stodg has it covered for the most part in his link.:smart:The biggest thing is get off the interstates and slow down. When its possible to get 14 MPG just cruising along with my setup at 55 MPH... I know I drop down to 9-10 MPG at 65 MPH. Also be aware most ST (special trailer) tires are only rated fro 65 MPH so its best to slow down and get away from the redline of the tires anyways.
