Welcome aboard, Tiger.
There's already a wealth of info for new owners here on SOC. I would encourage you to read as many of the posts and threads here as possible. Since SOC started up in 2006, there have been many, many questions asked and answered. It's probable that you will find information on just about any subject related to your Sunline that you might need.
The search function is very helpful when you have a specific issue you need help with.
After that, ask!
There's almost certainly someone here who can help.
