Welcome carroll!
Did you find the Sunny or acquire it or both?
If you can post a few pics of the other sides we can help you identify the model. If you know the year, you can download a copy of the original Sunline brochure for that model year and look over the floor plans to line up a match and the model.
See here for how to get to the FILES section.
Then go to Brochures, then to your year.
Hope this helps.
John
