We bought our '11 new. It's identical to yours except the floor plan.
While we had a year of debugging, not unusual for any brand, since then we've been extremely happy with our choice. It's our first DP, purchased as our "retirement home", and I wanted to do as much as I possibly could to avoid making an expensive mistake that we'd not be able to afford to fix. I did a lot of research, ended up with 4 brands/models on our short list, ultimately resulting in our ordering the Rev.
The '11 will be on the Spartan chassis, seemingly favored by those more experienced than I. It's old enough that someone else has probably gotten the bugs out for you, but new enough that you shouldn't expect any major system issues related to use.
Good luck, and let us know what you end up doing - and post photos!
