Half way there B-Double my first trailer build

[STI-REX]

This type of setup is small for Aus at 25 mtrs total length 1:1

But it needs to be taken into very tight spaces to load and unload and will be backed into and out of customers premises 10 or more times a day on metro work

also negotiating some of our roads 2 x long semi's on converter dollies would not make the turn in the metro areas

In the Outback (desert or mud hole seasonally dependant) they use some converter dollies on the Roadtrains but they do not generally come into big cities

Coupling over axle sways less than coupling after axle and is more stable under emergency braking (less jackknife prone )
