My 2011 has been great, a couple little things I did myself. We used it 3 weeks across country from a dealer pickup in the Midwest. The only thing of any import is I think I have a vent issue with the grey water, when it shows about 3/4 on the indicator the bathroom sink will start bubbling through the drain. I think the vent pipe might be down to far in the tank. I plan doing a little experiment to figure if is just an indication or real issue.
Thats it.
