When first we saw our 24.1 at the RV show it was parked next to a 25.3 , both being displayed by the same dealer.
We initially were going to buy the 25.3 but were talked out of it by the salesman.
He made two points , first he said that he had used a 25.3 for a weekend camping trip with his family.
He said that he found the bed to be uncomfortable. The reason being that when sleeping on his side the "hinge" where the bed folds when the slide was put in was exactly where his hip landed causing discomfort.
His other point was that while the slide was nice in the bedroom it was more useful in the "living" area .
Apparently during their weekend in the 25.3 a rainy day kept them in the coach and he said the dinette was not a comfortable area to hang out and no slide made it tight.
After listening to what he had to say we went back and forth between the 24.1 and the 25.3 , lying on beds and sitting on couches and dinettes .
We bought the 24.1 and for us it was the right decision.
This choice was based on our needs and wants, we bought what worked for us .
With that said the 25.3 may be a better choice for other folks , different floor plans fit different needs.
