My plans:
  • Clear windshield film - gravel impacts lead to expensive replacement. The film should block air leaving to a small pit, not an expanding crack.
  • Recling passenger seat - so it can become 'Hotel BMW'. A water and bug resistant tent with floor panels will minimize hotel/motel costs. Camp out at a free L2 charger <GRINS>.
  • Aero wheel covers - a significant source of drag, the spokes work like fan impellers. At least one credible SAE paper shows this is a significant drag source.
  • Aero mud guards - one in front of each wheel and possibly one behind to minimize the head-on wheel drag. If you don't let the air come to a complete stop, the drag goes down.
  • Tuff, ribbon, smoke testing rear body - mine has a 2" receiver so I'll make videos showing what the air is doing behind and under the car. Then I'm can make cardboard, bodies to measure their effects.
Accurate benchmarks, A-B-A testing, will keep me from fooling myself.

Have you looked at the YouTuber Bmwi3diy? he does lots of camping in his 15' rex, And the reclining seat idea reminds me a lot of the urban suite idea they had at CES2020.
