Welcome to the forum!
We have about 28K miles on our 2016 25.2, and well over 300 nights in it so far. You didn't say if you have any RV experience, or if this is your first. That info would help the group answer your questions. New buyers can forget to budget for repairs and can finance their way into serious upside down, where they owe much more than the rig is worth. For some folks, a 45 foot land yacht isn't big enough, while some folks live nicely in a tiny house. Different strokes...
Our floorplan is similar to the 25.3, except the bed slide goes out the rear. For us and the way the two of us travel (with no pets), the 25.2 is a good fit. Vegas and Axis are twins, with only a few styling differences.
There are good and bad reviews on every product. Keep in mind that the people who are unhappy tend to vent, and those who are happy are off enjoying the product!
Bad decisions make great stories!
