I've NOT used this product. I have seen lots of discussions suggesting that they don't work. I have seen lots of discussions suggesting that they're great.

Good luck in your quest for better fuel efficiency.

Take care,
I've watched mist and it swirling in the aerodynamic bubble behind trailers, it does change the pattern from a similar trailer without them. I'd like to see actual wind tunnel test results to see if that change actually reduces drag.

As they used to say- "Speed Kills"
Aerodynamics??? Slow down and smell the roses. What's the hurry if you are on vacation or retired.:-)

I am a big advocate for slowing down to save fuel. I suspect some RV manufacturer will eventually be the first to try this. Big trucks save over 6% in fuel with these trailer tails. When teams drive 250K a year, that can be substantial. For me, I average 5-7K miles anymore, payback on the hardware would take awhile.
