You do have a nice camper. The inside looks very clean.
The NADA site for RV's is a place to start. It assumes the tires are not beyond 5 years old. I included the power tongue jack, the stabilizers and a spare tire assuming you have one as those where options at the time Sunline made it. All the other features are part of the Solaris models' and are not extras. https://www.nadaguides.com/RVs/2006/...4087784/Values
The condition of the roof, caulking and any leaks, even is not seen inside but in the walls, floor or ceiling can affect the sale value.
Right now with Covid, campers are selling or were this past summer. Odds are high this coming camping season they still will be.
Hope this helps and good luck.
