This Mod unlocks all accessory parts at level 0. So you don’t need to Level up, to get some grills or lamps on your truck. It may be buggy for those, who don’t own all parts (for example RIMS DLC). It will show those parts ingame and clicking on them will lead to a crash. Sadly, there is nothing I can actually do with it. Just be careful and just use Items you know you own. It doesn’t work with modded trucks, modded parts or modded trailers.
