The original guy that owned the URL and created the subscription site approached the company and got their buy in and support. The company was an active participant in the forum with over two thousand posts. Then the original owner was approached by RV Life Network and promptly sold it. If you don't know what the RV Life Network is, it's a conglomerate of similar brand based web sites - mostly subscription based.
Grand Design no longer was interested in participating and pulled out, demanding that the new corporate owned web site infringed on their trademarks - don't blame them one bit.
Of course, they wanted to keep a web presence and continue helping their customers.
READ I have been on the receiving side of their customer support - even after my warranty expired and it is outstanding. So some of the mods there were offered gigs moderating a new web site where GD is again an active participant.
It's all about money, and no one here would do anything different. The new site is a great tool to get technical help and they don't tolerate bad behavior. Those that behave badly are not welcome, and that makes the site more enjoyable to use as you don't have to wear your flame suit like on other RV boards. There are plenty of critical posts to be found, but those posters are willing to discuss calmly and open to suggestions from others.
