Thanks, WE3ZS. Testing all 3 configurations is a good idea of course. (First I have to get the truck back from
autobody work.) I have a ScanGauge and have been pondering a good local course.
BTW, I think ABA testing would be awesome if someone had access to a big enough oval track with banked corners. Set cruise control, let wind cancel itself out around the circuit, and add laps if needed to iron out measurement noise. That would rock!
With #1 the handlebars (and I believe at least part of the headlight) would catch air coming over the cab. Also remember that the tailgate probably has to be down. If someone wanted to they could make it kneel by removing one or both wheels, or even just lay the bike flat in the bed for that matter. Those options are not on my table, however.
