Looking at the photos I notice they have aero wheel covers but no skirts on the one trailer. It would seem to be easier to the skirts and have more advantage. Or even better, both!
I see lots of MVT trucks with the tail, deployed. They seem to be hitting the aero mods hard. More of their trucks have wheel covers and tails than any other I see on the road. Now if they would slow down they might get even better. I go 61-62 and they blow by me.
I got 7.14 mpg Friday because of a tail wind all day. Usually I get low 6's. My truck has no aero mods except that I slid the trailer as far forward as weight will allow to reduce the gap between the two. Its a 2010 Cascadia pulling an intermodal containter.
