I'm with IndySam, please quote such a rule. I have read the manual many times and seen no such indication that descoring by any means other than tipping is invalid.

There have been CAD drawings on another thread showing a bot with a very short drivebase that COULD cover ~50% of the trailer, IF a U shaped robot is allowed to have its trailer hitch on the inside of the U (unlikely). Possibly you could add a big CIM driven fan, to help blow balls away from the remaining 50% of the goal, but I think this strategy will be effectively outlawed anyway.

EDIT: <G07> makes no mention of descoring not counting, only that tipping your own, or an alliance partners trailer (or even the other alliances, really) will not descore the balls already in it. I imagine this is because the GDC expects there will be some accidental trailer tipping, via high speed collisions due to the low mu.
