I can't comment on the 25.2 specifically but I can comment on the Axis/Vegas line since we have a 24.1.
They are well thought out units with minimal issues (for a Thor) so far. There have been reports of: Cracked windshields, bad fuel pumps in the generator (mine had this), bad windshield washer motors (mine also had this), lack of insulation under the dash, mud-flaps hitting the exhaust pipe melting the mud flaps, and other smaller stuff (I'm sure more will add to the list).
We like ours and try to get out in it as much as possible.
I believe there are a couple of 25.2 owners on here.
