I have the older 27n, when it was named Sunstar, but from what I can tell they are identical to the Adventure.
We love it, and everytime we look at upgrading, we don't find anything we like more. If the floor plan and the size work for you, go for it, I don't think you will be disappointed.
We have about 35,000 miles on it, including a cross-country trip of several months, and it has performed very well!
Best of luck.
