The term TMG (Touring Motor Glider) is new to me.

In Europe, TMG is a well defined term and a TMG needs a different rating
than just a glider rating with a "mere" self launch endorsement. (It's
even more complex: You can choose between achieving the TMG rating as a
type rating for power pilots and as an additional rating for glider pilots.)

It's well possible that in the USA, a TMG is just another self launching
glider. I don't know. Anyway, I know of one commercial operator of a
Katana Extreme (aka Dimona) in Arizona: http://www.skykingsoaring.com/.
