Here's the pics of my friend's rack system.
Advantages: super quick to remove from a trailer so you can haul something else.
You can fit more in the trailer because you can load easily from any side so you don't
need a 'walkway'.
Can be customised to fit any model/models & can be changed easily to suit different models.
Disadvantages: You have to build it (although you would have to build racking in your trailer anyway).
You have to have somewhere to store it when you take it out of the trailer (although you could use it
as a workshop model storage rack if you have enough room).
