Deborahheinz Report post Posted November 9, 2023 I have a 2005 Southwind on a Workhouse chassis. I have been noticing a “popping” noise after I pull in and shut the RV off. It’s coming from the back end where the gas tank is located. This week I stopped for gas and it was nearly impossible to get the fuel tank , aka gas tank, lid off. When I got it off it popped like under pressure. I filled motorhome and came home. I’m thinking I have a blocked gas vent? Share this post Link to post Share on other sites
rayin Report post Posted November 10, 2023 I can remember reading of a similar problem, and the cause was a charcoal canister attached to the frame. That's all I remember. Perhaps a GM truck repair shop will know. Share this post Link to post Share on other sites
wildebill308 Report post Posted November 10, 2023 I think Ray is on the right track. I would also do a search on the canister. I bet it just need to replace it. Bill Share this post Link to post Share on other sites
