I've had a Vegas 25.2 for close to 2 years now, For the last 2 months, I have been full timing it as I look for America. The Vegas is a great rig for one or two people. Rent one for a few weeks and see if it fits what you want.
The size of the Vegas was imortant to me. It really does have a scosh mor manouverabilty, Also some National Parks have size limioyts of around 27 or 28 feet.
I chose the 25.2 for it's queen bed and walk around capability. It is easier to make the bed. Also corner beds can be inconvenmient for 2 people. On the other hand, a friend of mine has the 25.4. That model has a HUGE basement.
Most of all, have fun!
