Unless it's something that would come straight off without any effort like a magnet, a sticker on my rig would earn you a punch in the ball sack.
I bought a truck a few years ago and it had the dealership sticker on it, I took it home and took the sticker right off. Brought the truck back a couple days later for a detail and they put another sticker back on. Brought it back again and made them remove it and detail it over again. It was actually a really big pain in the ass to even get them to just remove the stupid sticker.
