replacing spoiler on rpod 179

Originally posted by GlueGuy IIRC, Stephenh had tried the Purpleline Aero. I don't recall whether he felt it provided any benefit or not. Kind of noodling out loud is whether a reverse spoiler would provide any benefit? Something that was actually curved downward and sitting above enough to encourage the airstream at the back of the R-pod to stay attached long enough to fill the vacuum bubble.

I found more benefit when we had the Escape and not as much with the Frontier. This is mainly because it sat closer to the RPod on the Escape and the Frontier, even with the tonneau cover, has the 5' bed space between the AeroPlus and the hitch plus the additional distance between the hitch and front of the trailer. It still helps deflect some of the bugs though.

I found that software and I'm working on getting some new airflow videos now. I'm using my 179 and Highlander TV.  One problem with the models in those videos is that it looks like the Reynolds number might be set too low, allowing for some laminar flow, which we don't have at the speeds and dimensions we're working with. I reset it higher to get rid of that. 

If anyone wants to fool around with this software, here's the link, its pretty easy to use. The hardest thing is to get a good photo uploaded. Stand way back when you take the picture. You have to use a .bmp not a .jpg and it can't be wider than 1400 pixels. To get rid of the background you can use Paint and carefully cut everything else out so its all white except the trailer and TV. Once you get the profile in you can draw in whatever aero feature you want really quickly.
