Congrats on your new Sunny!
We can help you back into a year and model but need some more information to help better.
From the limited number of pic's, this much we can tell, it is a late 80's camper, possibly a 1987 thru 1989. I cannot see the front wall decals close up enough to hone in on a year. Sunline changed decal colors and patterns and main siding color or other features as the years went by. By 1990, the main siding was changed from tan, back to white, so we know it it not newer then a 1989 on a camper that large.
As for the model number of the floor plan, we need more outside pic's to show where the windows are and inside pics help too. It might be a T3200, a T3070, or maybe a T2862. The front end of those 3 models are close to the same. It looks big enough to be a Solaris, (a trim family of features) but need more info to confirm.
Starting at the dinette to fridge wall left to right and walking towards the back part or the camper, a lot of features change between the floor plans.
You can help yourself too backing into a year and model. If by chance you have a VIN number, we can tell the model year in the VIN.
We also have sales brochures of many of the Sunlines in our FILES section. You find the year, then download a copy and line up the floor plans and color schemes. Look in the 87,88 & 89 year.
To get to the files section, you need to be logged into the forum.
At the top of the forum are tabs, look for the word "FILES" click it.
Once into the files section, scroll down to the "Sunline Brochures" section. Go in there and find a sale brochure for the camper year you are looking at and down load a copy.
Hope this helps,
