Trailmanor pricing

Hello, long time reader, but first post and new to the camping world. I wanted to get the opinions of Trailmanor owners here to see if I was getting a good deal. I have an opportunity to buy a 2011 2720SL for $15900. I looked the trailer over today and it seemed really clean and in like new condition. Now mind you I really have no idea what to look for so I was hoping for help. What specifically should I pay close attention to when looking at used Trailmanors? Does the price seem right for a 2011 2720SL? And my TV is a 2006 Honda Odyssey. Based on what I have read on the boards, if properly equiped this should serve just fine as my TV, correct? Thank you so much for your help.
