nealday Report post Posted April 28, 2021 I have a 2006 Winnebago Adventurer, on a workhorse chassis. With the 5.1 motor. The emission stickers are missing. It makes it a pain to get the emissions done on it. Does anyone know where or how to get new ones. Thanks in advance Share this post Link to post Share on other sites
rayin Report post Posted April 28, 2021 (edited) Try contacting GM customer service national office. The emission stickers are/were required by law on new vehicles, there should be a resource for replacements. The same information should be in the engine owners manual.
