Name change, possible because of a change in trim levels, but can't say for sure.
We have had our 06 29b for 7 yrs now, bought new in May of 07. Only one major problem with the coach portion, living room slide shaft on the motor had split lengthwise, service depart said that they had never seen a failure like this before, (defect in metal shaft). and on the Ford side, a leaking pinion seal.
Just regular maintenance, especially checking the caulking on the roof, major point to check is where the fibreglass roof panel fits into the sidewall extrusion. After 5 years we found several cracks. When talking to our dealer/salesperson, we told them that you sold us a unit that suits our needs and has virtually no problems wo why trade.
We found that everything is usable when the slides are in, tight getting between sofa and dinette, but usable. Can' hang feet over end of bed, and I have to climb over DW to get to my side of bed, but once in we are comfortable.

at 7 years old carefully check out tires, for date and cracking. If it is the original owner selling,(8000 miles) the tire may look like new, but will need replacing, that era of Michelins had a history of cracking. Also check generator for hours of use and does it work,
