Jayco Greyhawks are excellent as far as comfort is concerned. High quality cabinetry and fixtures, etc.
Just be aware that all that higher end stuff weighs more, and Greyhawks often end up quite 'porky'. Its not uncommon to see them with less than 1600 pounds OCCC left ... I was 4th and inches from buying one myself but pulled out due to the meager OCCC allowance in the coach. My Winnie has less content, but 1300 pounds MORE OCCC than the Greyhawk I was considering. Of course my toilet is plastic, not ceramic. Plenty of differences abound, but I can pretty much load mine up w/o worrying a whole lot. It was the trade-off I was willing to make.
Just be warned and check the yellow sticker on anything you buy.
