I forgot to mention that always traveling down wind is one of the most helpful things you can do to improve mileage.  ............

I have a 2015 Nissan Frontier 4x4 V6 SV towing my 179 I get between 10-14 mpg with over 30,000 miles towing the 179 that has been a consistent average, I stay under 65 mph.

The best gas mileage I ever got was when I owned a teardrop, as the trailers got larger the gas mileage went south. If your concerned about mileage, best you don't tow. Big truck is not the answer and some of the new motors make improvements, but end of the day - you can't tow anything without reduced mileage. Not a big fan of wings and such, you think works and it may in a limited capacity, but bottom line is you add the weight and drag it against the wind, the mileage suffers.

I wonder if making one of those folding thingies that are often on the back of van trailers on semi's would help much?  On the other hand, in a strong cross-wind, it may be a little more exciting than I want to experience.

Certainly not in my planned mods.

Interesting discussion, our Venza Crossover puts the high backend closer to the Pod than a pick up but has no provision for a roof spoiler.  I have read a lot about the AirTabs but find the price at $2.00 US each pretty high as my rough calculation figured out at about 150 to 200 to do the sides, spoiler and AC.
Experience will tell, plus I am sure the price will come down as AirTabs become more popular.
I do have a question though, truck sites say that the closer cab aerodynamic devices are to the trailer the more positive the effect.  Would a light tarp between the top of the TV and the top of the Pod work if the dynamics of turning could be figured out.

I would think that any sort of fabric would just flap and buffet in the wind. I'm no expert though, so happy to hear what others might have to say.

In about the 2nd year of poddness, we had an owner do a ton of experiments with aerodynamics, including putting about 200 air tabs on his Pod.. didn't do anything measurable. You will have to go far back into the archives, but the info is there..

I see no way to build a fabric bridge that would survive.. I have talked to fulltimers with 5er's, who say a spoiler at the rear of the cab was worth .5 to a full 1MPG.. doesn't sound like much, until you start talking a rig getting 7-8 MPG.. then you are talking a 15% improvement...

That pretty much lines up with my understanding of the dynamics. If you're already getting 12-15 MPG, then you may very well be at the best you can get pulling a pod. If you're in the 7-8 MPG range, then a 1 MPG improvement might be worth a few bucks.

Let's see, 1 MPG better than 9 MPG at 1000 miles... you would save around 11 gallons. At $2.50 per gallon, that comes to $27.

Best ways to improve MPG: Change your driving habits, no rapid accelerations, excessive speed (60 mph plus), use cruise and overdrive, use dash AC only when needed, no excessive idling. Load and weight correctly Maintain your TV and your TT, tire pressures, air filters, sensors, oil changes, wheel bearings, etc. Some say use regular gas unless required.
