I agree for most gliders, but the Genesis-2 tail dolly must remain on at all times while on the ground. If the tail dolly is removed the wing assumes a high angle of attack and a 5 knot wind will move the ship. My dolly has a built in lock that prevents rotation and I chock both wheels if I leave the ship unattended.

My wing dolly has a parking brake, and is fairly heavy. With the parking brake applied the glider would be stable even with the tail dolly still on unless there was a substantial wind. That said, I do not leave the tail dolly on when the glider is unattended.
