Iíve tried both out.
I started getting a lot of spam from the yahoo sunlineowners group, so I got out of that one fast.
I'm still in the other yahoo group, but very rarely, if ever, visit it.
I've found this forum to be the best.
Great bunch of people here with a wealth of information.
There's also RV.net forum. You can get a lot of good information on that forum also. But you can also get some rude replies to your questions. Something you never find on this forum.
That's what's so great about this forum, you never have the rude replies or fights that you see sometimes on RV.net. Plus here, everyone are Sunline owners so you get more specific answers to questions on your Sunline that you might not get on RV.net
That's just my $0.02.
