We're glad you found us.
Hey could you do us a favor and tell us what model YEAR your Vista 30T is? Winnebago has produced the Vista for a number of years and they are known to constantly make changes each year... sometimes twice a year.
UPDATE: I found your year was mentioned on another post - but creating a Signature (see below) is still the best way to go.
The best way to get help is to always tell us the Model, Floorplan (30T for example) and the Year. And you can either type that into every post you make OR better yet is to click on the link in the menu bar above that says "UserCP" and when that opens there will be a menu on the left hand side of the page. Just click on "Edit Signature" and put your info there and hit save. That way whenever you make a post we'll all know exactly what Winnebago you're talking about.
