Glastar
Yes it is a neat wing fold - but...
You really need to make sure there is a minimum amount of fuel in the tanks - otherwise it is difficult to disengage / reengage the locking pins. If you do fold the wings with a significant fuel load the aircaft with sit on its tail due to the c of g movement. And if it sits on its tail the fuel vents overboard.
Putting an aircraft as large as a Glastar on a trailer has more than one or two challenges as well. It can be done but it is a big trailer and needs to provide additional support to the tail and wings - so it starts to look complicated.
In practice my friend has used a large flat bed trailer a total of once in the near 6 years he has had the aircraft - for the initial movement to the strip.
