I don't think this would be a problem if you order both the wings and the fuse at the same time. Reason being is that you can't get the spar carry through section with out the wings because they are a match drilled set. I think you build up that carry through section fairly early on in the fuse build. So, if I am recalling correctly on this very same question I asked last year around this time, I was told this was the reason you can't.
Good points. The other poster who is building an RV8 checked with Van's and they told him no problem. Of course he could have been talking to Gary the night janitor, who knows? I forgot about the longerons. I guess Van's could ship them in a 15' long tube.
