I think my single wheel trailer based boat tail has many different aspects to it. Most of it pertains to the approach of the build and not so much fer the actual aerodynamics of it. As far as the gap covers go, it's been very interesting to attempt various solutions fer the dynamics of the mechanics.
So yer saying that gap covers between the trailer and truck have no actual bearing on the aerodynamics of a boat tail? Interesting...
But how will I incorporate both of them into one complete vehicle? I guess that's one of my goals.
