Tom and Fran,
The replies you are getting are "right on". Having a program with official named ambassadors was a goal of mine. We tried it for a year or so but it was very difficult to get campgrounds to agree to allow the ambassadors to hold open houses at their RVs - though some were done.
As others have mentioned, we have hundreds of unofficial ambassadors out there who love to talk about their product, their club and the fun they have with both. The Heartland Owners Club has grown steadily since we formalized the club in late 2008. In the last year or so, we/ve net added 20-25 members.
Thanks for the question - it was a great one. Hope you can make a rally or two this year and by all means, read your quarterly Heartland Highlights newsletter from cover-to-cover to keep up with the happenings. A new one will be out in a week or so.
