See the Wing Rigger atwingrigger.com

You don't need to shy away from heavy wings anymore because Mesa
Inventore Corp, has a slick 3-wheel "wing rigger" that rolls just fine
over rough ground and the third wheel keeps it standing upright
without the little stabilizing bar that always seems to dig into soft
ground. Breaks down into small pieces. I'd consider ther LS-3 a good
candidate with a Wing Rigger, so is the DG-200, etc. E-mail me for the
address for Mesa Invention Corp.
