I converted the included JPEG to a PNG so I could add this texture, but as soon as I add it I get a "Couldn't load vehicle" error when trying to spawn it. I changed the name to "nsandstormtemplate_sign_9" since I have a bunch of other skins for this truck that are working. Any idea what I could be doing wrong?

Nevermind, got it going. Forgot the livery limit is 8, just deleted the template livery and renamed stuff appropriately. Looks mostly good, there is a weird vertical line on the left rear door but I might edit it myself. Thanks!

I fixed the lines and added a Commercial Vehicle Enforcement badge, would you mind if I upload that, assuming I give you credit?

@adkmac Sorry for the late reply, But yeah that's good with me.
