Roextended Project

I'm wondering if I want to use a company addon for when I am hauling outside Roex's area, will this overwrite the various skins to Roex's traffic and company skins ?

If so, how do I avoid this as I want to keep Roex's skins for traffic and companies; do I need to make an exclusion or delete something from the company addon I choose, or is it enough to have it beneath the Roex files in the load order ?

Traffic or company mods are not changing stuff we created as standalone stuff, i supose they change stuff from base game. You can use them with no problem.
