Considering JAY FEATHER ULTRA LITE FLOORPLAN X23F?

We will soon be in the market for this three-bed floorplan. Are there any significant advantages of any of these models (Coachmen, Rockwood, Jayco) over the others?

I know the Jayco comes with a 2-year warranty. I seem to recall that you can optionally purchase an extra year of warranty with Rockwoods.

Is the bed/canvas system of any of these superior to the others?

Thanks everyone!
