As far as the Sticker, We did this with our Dodge truck club. It was best considered to give the group a name. This way it didn't look like we wanted people to check out a Dodge web site. We were the New Jersey Rams on our Decal. Of course with the website.
For instance we could do something in the lines of "The Keystone Nomads"
www.keystoneforums.com. With a crafty design on a "bumper sticker" that gets placed on the front tongue section so it can be seen by campground walkers would be a great way to find a fellow web siters or get someone asking that has a Keystone product. Who knows?
