I asked the same question "forum for V-nose owners" when we bought our 2015 2618 Windjammer.
To be honest I just discovered the V-nose owners forum. But I have had great success with posting to the General Discussions Forum. I just try to make sure that Windjammer or V-Nose is in the post and they will find you. Sometimes you can get helpful in-puts from non-jammers.
...my DW and I just spend 3 weeks ours and we are looking forward to our next adventure.
Good luck with your new Windjammer
