Welcome from Colorado: British Colombia is one place in North America we hope to visit with our Airstream some day. It is a very lovely place.
Welcome to the Airstream Owner's Forums. Yep, you can post a question in the appropriate Forums category, such as plumbing, and folks will help you out. If you plan on extensive renovations or remodeling, then as Bubba L suggests, go down the the Knowledgebase near the bottom of the Forums page, find the model Safari and then your model year. There you will find like minded owners who may have specific knowledge of your issue.
Post a photo or two of your new Safari. The 25' length may be Airstream's most popular size. It is just right.
