We like our 25.2 floor plan, and prefer it over the 25.3 for the way we use our Vegas. We like the solid bedroom door, versus the curtain in the side-slide model.
We have learned to list our length as 28' for state park campgrounds, due to the rear slide. Our last coach had slides on both sides, and we always had to make sure there was room to put them out. With the 25.2, that is never a concern.
I miss the small side windows in the bedroom slide that our previous coach had, but we love the size of the shower in the 25.2, even though we are not plus size people.
If you could find a dealer with both models, the best thing you could do would be to spend some time in both, and think hard about the way you would spend your time in them.
Bad decisions make great stories!
