This mod adapts to v1.54, Volvo FH Tuning Pack, and Updated Cabin Accessories Pack.
From v3.1.54, this truck is available in “Used truck market”.
If you want to buy a new truck dealer, please let me know. I made addon mod.

Note
Most of the part names have been changed.
So, your choice is in two ways.
1. Use the command “g_remove_missing_accessories 1” and purchase new parts.
2. Sell the current truck and buy a new one.
