I'd love to see some ABA test data.
I've been carrying a small motorcycle across the front of my truck.
I did not do ABA testing but tank MPG data over a few years and several thousand miles suggests the impact is not as bad as one might expect. My "read" of the data shows 16 +/- 2 mpg without the bike versus 15 +/- 2 mpg with it on front. Of course I'm counting on my trailer to clean up the wake.
I did see the engine run hotter with the bike on front. That seems to help FE but I haven't tried to tease that factor out of the data scientifically.
I'm not sure this anecdotal case helps any but there it is.
I suspect there is motivation other than aero for moving the spare up front. Aft to fore axle weight shift for example. I'm curious about the "rest of the story" as Paul Harvey used to say. (wink)
Rock on!
