Articulated Truck, what´s wrong with my code?

[temporal8]

Hello, I am trying to make an articulated truck and I succeeded, however I think my approach is wrong.

I defined vehicle flatbed_realtruck_12_1 as the trailer and vehicle flatbed_realtruck_13_1 as the truck that uses flatbed_realtruck_12_1 as a trailer, obviously the problem is that the trailer appears as road vehicle in the purchase list just before the articulated truck.

Nevermind, i solved, i just modified climates_available to 0, In this way the trailer does not appear in the purchase list.
