We purchased a 327RES about 2 months ago and for the most part it is a very nice camper. There are a couple of small issues that you should be aware of.
First, the 60 gallons of gray capacity are actually two 30 gallon tanks, one for the galley and one for the bathroom. The 30 gallon bathroom tank of course fills quickly with showers and does not overflow into the galley tank. This has been a huge disappointment for us and we would not have purchased the unit had we know this in advance.
Second, because of the way the bathroom door opens it is impossible to enter the bathroom from the bedroom without stepping down the steps, opening the bathroom door, and going back up the steps. It is a very poor planning of the bathroom entrance. A pocket door would have been much better.
Other than that, it is a great camper so if you can live with these two design flaws it will be a good buy for you. GB
