Considering purchasing a TrailManor

Good evening, all.

DW and I are considering a possible move from our current Fleetwood Westlake pop up to a TrailManor. I have been looking online at different models both new and used. I have found a pair of used that have caught my interest. The first is a 2007 2720 and the second is a 2006 2619. I have Googled all I can think of but am unable to find specifications regarding either model. What size wheels would these units have? Will the axles be of the easy lube variety? On the new side I have found a 2011 leftover 2720. Are there significant differences between the model years of the used and new?

Any assistance is greatly appreciated.

Thank you in advance.
