Hi Ashlee!
Welcome to the club and congrats on your new sunny!
If you go to our "FILES" section there are copies of the original sales brochures there that you can look at and match up your floor plan to back into a model number. Plus there is lot of other good info in the Files section.
To get to the section, look at the top of the forum page for the word "FILES". That is a clickable link. Go in the Files section, select "Brochures" then scroll to 1985 and download a copy of the brochure.
The Seville line of campers, use to be their higher end ammentity campers. You did not mention if the camper was a travel trailer or a Fifth wheel. In the brochure, travel trailer models start with a T-XXXX number. Firth wheels start with and F-YYYY. Truck campers, if they made a Seville in that line, would be a C-ZZZZ.
If you cannot sort out the model number from the brochure, attach some pictures of all 4 outside walls looking straight at the wall getting the entire wall in the pic. And a few from inside and we can help you back into it.
Hope this helps and looking forward seeing and hearing about your Sunline adventures.
Any questions you have, just ask away. We have a lot of posts allready on most everything, but we have no problem trying to help on a new question.
John
