I have redone the attachable trays completely, they use the same tray as the Volvo.
The dog tray connects to Carvers 5 axel dog trailer. The truck tray connects to the following trucks: Volvo 2×4,4×8, Tork’s Hino, Carver’s k108 and T900.
The Trays have autoload but it’s no longer a dependency so you can use the trays without the autoload mod.
Simple Ic is used to change the rear signs from Road Train to Oversize and there is also a trigger to hide these if you don’t want them. One trigger on each of the signs.
They will take my attachable forklift once released and they also take the attachable forklift on kings at the moment.
Both Trays have loading ramps these will fold out using your fold key.
