We have a 2013 23b. For the most part it is a great camper. Thanks to either Jayco or great dealer prep, ours had 0 defects when we took delivery. Ours had an awning recall,but the manufacturer did the repair in my driveway within 3 weeks of the recalls announcement.
We have heard many people complaining about low sewer clearance, but in thirty some camp sites we have never had a problem. The u shaped dinette that many don't like is not a problem for us,it just doesn't bother us.
The one real and major complaint we have is the shower. 2013 had a shower pan,not a tub. We had to resort to an ugly magnet and weight system to keep the curtain in place so we don't soak the whole bathroom.
Carrying capacity is very low so your TV is going to end up loaded while you try to minimize the trailer. We do keep our food, kitchen tools, and bedding in the trailer but camping equipment,(table, lanterns, grill, etc, .are in the truck. We travel with only about 10 gallons of water.
Other than those concerns,we are very happy campers.
