ProMods

promods - standalone..

Replacement. (But then make sure you don't use SiSL's replacement add-on simultaneously.)

EDIT: No CAPLV, he or she doesn't want standard SCS trailers.

Standalone changes the companies too! Replacement is bad because it will make the Italy and France companies giving whites cargoes! You still gonna have the jazzycat trailers on IT and FR companies but most of their trailer will be white!

I use jazzycat pack and a part of TCP because i want the original companies! So i only activate the trailer mods of TCP but not the comany ones so i get the trailers of TCP but not the companies since i don't like them! I combine that with Jazzycat pack! But i'm a different case since i like the original companies!

i`m using tcp standalone w/companies + jazzycat.. no any problem.. for compatibility its better.

The companies are changed by the two company files that are contained within the ProMods TCP mod.
The trailer skins are handled by the Replacement (matches the trailer skins to the company replacements) or the Standalone (SCS trailer skins are kept, new skins are added in) definitions.
The next version of the ProMods TCP will take care of the white trailer problem when using the Replacement trailer definitions. I've submitted the fixes to ScuL already and we're just waiting on the testing to be finished.

Many thanks indeed for all the replies guys, it's very much appreciated.
Judging by the comments, it's definately the 'Replacement' file that I should use.

Great to hear that you got the information you were looking for!

Ever since i've got 2.30 in, i can't seem to load any of Jazzycat's packs. Without them, the game loads like 10 secs. If i put in Trailers and Cargo, it takes at least 10 mins. I tried Railway and Military Cargo too, same time to load. I've tried them in different spots in load order with no improvement. I never had this problem. I do have other map mods like Rusmap/Great Steppe and others loaded, but never had a problem with his packs before.

I just really want his cargo, but don't want to sit at a loading screen for 10 mins.

Here's my gamelog (It does have some garage errors cause i tried to load Russian Open Spaces, but it didn't work so i took it out)
