I've done many semi's tractors and some full length 53' trailers, they are just as easy as anything. I have a great person that I send pictures to and she can make me a vector file for any image I send her, this would probably run you 60 for a vector image, just going off what she has done in the past for me, it's so worth it to have a contact that can do that. I can match any logo, any art, anything all because of her. She is amazing. Removing the old with be your biggest time issue, maybe have a second set of hands on duty that day, because some are easy, but you don't want to damage the surface, and if they have a lot of rock chips or scratches all ready, that makes it a little more difficult... but you'll be pleasantly surprised how easy it is... have supplies on hand, and do it inside, if you can... a slight breeze can sneak up on ya and cause a mess... Good Luck, looking forward to before and after pics!
