I'll share our reasons for choosing the Vegas 25.2, but must say first that it's different strokes for different folks, We've had ours for just a couple of weeks and about a thousand miles, but put a lot of thought into replacing our last coach, a Class A. So far, we are delighted.
I really wanted a smaller coach, like a Travato or a class C, but they all had too many sacrifices for us. 2 friends bought new class 'Cs with corner beds. One of them asked me on the day they brought it home, "How do you make this corner bed?" They hadn't considered making the bed, or crawling over their partner to get in and out. We wouldn't have purchased a Vegas model without the walk around queen.
We needed more storage, in and out, than anything less afforded us. The Vegas has an attractive price point, especially if you can deal with an RV dealer in Indiana or a surrounding state, and diy the delivery.
We also liked that we could tow our small car with the Vegas, something too much to ask of smaller rigs. The front seats swivel, giving you more usable living area. I like having no side slides, so less worry about mechanical issues and leaks. I have experience with diesels, and didn't want to pay the premium for the engine or the fuel.
For us, the Vegas is not too big, not too small. Just right. Easy to drive, easy to park. Ask me in a year if I still am happy. So far, so good!
There are friends, there are family, and then there are friends that become family!
