The non-demo from the back lot is the one I almost bought 3 weeks ago. They had it all setup in back, right? If you are willing to drive to South Dakota they have another 2005 Baja and then there are 2 more at their other store farther east.
The 10RT you got is a good unit, you will like it. The differences amount to preference. Both campers will do the job.
