Flatbed truck transport of glider in trailer?

I am trying to move a glider and cobra trailer from CA to GA. The obvious choice of having it towed is my first plan.
I have been offered to have it transported on the back of a flatbed trailer behind a truck instead.

Just because it is not the normal way to move a glider & trailer I wonder if there are any problems with this idea. I don't know if it is better or worse.

I would imagine that you would have to chain it down to prevent it from moving up and down or fore and aft so that would reduce the protective function of the trailer's suspension.

So then I would imagine the heavier flatbed trailer has a stiffer suspension.

There is also the possibility of the interaction/amplification of motion if the two suspension systems both move.

Then I wonder about loading and unloading up and down an angle and all the things that might go wrong.

So the list of unknowns makes me hesitant to do this, or does anyone think there is an advantage to this idea?
