Jazzycat trailers are one of the best and it’s a pity there are not more in traffic. My mod is just an addition to jazzycat trailers and cargo pack v6.3 that brings in traffic more than 50 special cargoes in traffic.
Moreover I gave higher spawn to these cargoes also for few more special cargoes already included in traffic by jazzycat.
for some cargoes I had to change the traffic trailer into a non-steerable trailer (steerable axles are not yet accepted in traffic)
the zip archive includes a 2nd optional mod that remove from traffic some box trailers.
place any of my mods or both, above main mod, jazzycat trailers and cargo pack 6.3 or above.
