Awesome mod this with great potential, too bad SCS didn't chose to have this from the start as in Swedonia most trucks/trailer combinations are mostly the tandem with steerable* front axle.

Which leads me to my question, those steerable axle trailers aren't available as WoTr cargo?
I've been driving around to different towns but I haven't seen any :/
They do show up in the normal freight market, where they are also customiseable.

* Dunno the english term for them...
