Any Long Haul Drivers here? Options

I'm curious about the trailers that carry cargo containers.

-how are containers attached to the trailer? Do they ever come off?
-does the trailer flex?
-does it drive any different than a standard box trailer?
-anything interesting with these?

I believe there are two types of trailers for containers. The standard flat deck, where the container is loaded on and it is bolted/clamped at the corners. There are flanges which mate to the ones on the container or a standard flat deck where they clamp the trailer down, using bear type clamps. Used for small containers 20' - 30' And a dolly type arrangement where the wheels just go under the container and it acts as the trailer itself. The 40' type.

On ships they use large threaded rods and turnbuckles to clamp the containers to the deck and then to each other.

I know it costs 10K to ship a 20' one from Australia to here.
