There was another post about this, and it got me thinking. Not sure if I'm worried about someone stealing my gas, but I was thinking a locking gas door would be easy. I'm sure winnebagoparts.com would have a lock like the one that's on my water door. They could probably even be sure it's the same key.
Yes Steve, one the first things I did after bringing the Itasca home. I purchased a cylinder lock from Lowes the same diameter as the original closer. They come with a couple different length blades on them. I modified the blade just a little and it worked perfectly. Two keys and a lot of peace of mind at todays gas prices. 20 minute job at best.
