RV companies advertise wonderful construction and features, but they can change whatever they want whenever they want. Their bottom line is money, not your happiness. The construction on my 2017 16XRB seems adequate so far, but the model advertised and shown to me, the one I ordered, had galvanized steel wheel wells and a fan in the bathroom. The wheel wells were a tipping point in the sale. Two months later I was delivered an August, 2016 build 16XRB with plastic wheel wells and no fan in the bathroom. Very disappointed with that and extremely disappointed in Jayco's response: too bad, that's the way we make them now, now go away and don't bother us. Jayco was bought out by the Thor Industries conglomerate on June 30, 2016. I suspect there has been some cost cutting and disregard of the exceptional standards for which Jayco has always been respected.
