Transport truck "Trailer Tail" - aftermarket aero kit ~5% MPG improvement (video)

[blackcivic96]

Hey guys,

I know this is an old thread, but I actually saw one of these on the highway the other day. And yes I see a a ton of side skirts, plus extended front lower dams.

I saw dozens of Mesilla Valley Trucking Co. rigs sporting the Trailer Tail.Not all had it,but most did.Other trucking companies were represented as well.
Also,one Mesilla Valley rig had full-height,downwardly angled, elastic trip-strips attached to the trailer van,preceding the tail for approx. 3-feet.
I presume they are there to energize the boundary layer leading onto the tail.
It would be my wish that that the tails extend all the way down to ground clearance level.Splash and spray during rain squalls behind these rigs is still so bad that at points I pulled off the interstate to let the storm pass.
I never worry about truckers,but some motorists appear to have a death wish.They'd drive blindly into a Waring blender.

just came to see if anyone had posted about these before so i figured i'll add into this thread too. just drove 1800 miles this weekend and saw lots of trucks with trailer skirts but only one of these. Caught my eye enough to take a pic.



i wonder if there have been any studies over real world fuel efficiency gains from having this thing on?

well, I can tell you this, no trucker is going to run with that if it doesnt work!

This week on a road trip I saw one of these up close and personal. Then I saw an inflatable one. (No pic - I was riding motorcycle.)
