Look for : "Templates for modded trucks & trailers"
further down.
There is a list and a download of 1.26 GB that includes the GTM Peterbilt 567 templates.

I use ModStudios2 and paint.net. i can skin trucks fine, but like the pete 567, and freightliner cascadia do not show up in the skin list, but they do in the mod list, I do everything by the book, however neither shows up in the skins list. I have switched to UV and back but still nothing. Any help would be appreciated. Like I said though, it only happens when skinning the pete567 and the cascadia.

Does the game log mention anything?

Not that I saw (there's a crap load of stuff) but nothing specific. There are a few "warnings" on stuff that does work but nothing I saw related to those 2 truck skins. I have other skins that do work, but they are from the old mod studio design.

Post your game log.

My usual errors when paint jobs don't show are typos or forgetting to name them correctly so another paint job that's above it in the mod order takes it's place.

the log is way too crazy long to post, it wont let me

All my new paints are top of the list, done exactly like all the others. No spaces, capital letters, etc. As Modstudios2 warns me when there is some out of bounds like that

Got it.......wrong templates even though they said the correct name. Thanks yall for the assist

A wrong template shouldn't cause a no show in the mod list though, but glad you got it sorted.
