thoughts on this unit,,price ? quality ?

Seems about right but always room for negotiation.

What about the price

Here is part of a review:

"On the highway, the Vista handles with the agility of a drunk elephant. Tug desperately on an ear to change a direction, only to feel everything going a touch squirrely, then yank on the other side. It’s a constant balance of wheel motion to keep it in a straight line. The first 60 miles were harrowing and full of little yelps whenever anyone would get close in an adjacent lane. But after that, it all began to feel normal. Eventually, after not too long, you can actually settle down and relax a bit.'

There is a couple that put out youtube videos of their travels that are full timing in a Winnebago Vista 27N (the slightly larger triple slide version) that you may want to watch Moving Forward RV Videos As I recall they have had no major issues, and have only been into the shop a handful of times in the last couple of years with the Vista, most recently for a failed rooftop air conditioner, which is something that can happen to anyone.
