Congratulations and Welcome to the Club!
Maybe I shouldn't repeat what I said to Pynecone, however, you'll find a wealth of information here, specific to your Sunline trailer, as well as meet some of the nicest people that you may ever camp with.
I just returned from the first annual Eastern Meet & Greet and had a fantastic time. Hopefully you can join us at one in the future! Best wishes and Happy Camping!
