Hey orbywan! No apology needed. I enjoyed meeting too. You were busy then (a good problem) so thanks for making time.

I really don't know how much strakes would help. Maybe none but others use them and you seem the build/test type so it was a logical suggestion.

IIRC most of your MPG gains followed the boat tail extension; not so much the belly pan. I could easily be wrong but given overall dimensions maybe there isn't much room for improvement underneath. The rig is so many times taller than that gap that I suspect the tall sides are the best point of focus. Have you already tried tuft testing with a chase vehicle and camcorder?

Looking forward to future updates on whatever AeroRV work your schedule permits.

Rock on!
Bob
