Hi Mark Pittman, I have a 2012 Cardinal 3675RT and really like it. The aluminum floor/wall/ceiling frames are welded (not screwed together), the fit & finish is fairly good. While most folks put these rv's in the mid-level range, they are very good for the money. Having looked at the higher end brands we came back to the Cardinal. Your price of $23,858 seems fair enough, but you don't list all the "optional" equipment so it is not conclusive. The Nada Guides (
www.nadaguides.com) show the 2009 Cardinal 30QRL (with no options being selected) at $21,850 Low Retail to $26,300 Average Retail. So, I would think your unit is in the ball park.
When you do go look at the unit, pay close attention to the caulking/sealant on all the exterior joints, especially the roof area. Don't be afraid to climb up there and take a good look at the roof and the sealant condition. This is one of the most important areas to keep in check. Also, a good thorough look into the outside storage areas may give you an idea of how well they took care of the unit. If they are clean and debris free chances are they kept the unit clean & neat and took care of it a little better than the average Joe. Good Luck!
