Purchase opinions needed please.

[Narnia]

Hi everyone, we are newbies. We have a choice of 2 DRV MS units with the same floorplan. I wonder which you would choose?

1. 2008 with 12 cu' fridge, has cracks in the rear cap in 4 places. $22,259 out the door at a dealership.

2. 2010 "like new" as described by private seller, 8 cu' fridge, for $29,999.

Thank you in advance for your experienced help!
