I would say 11g from a dealer is a decent price. We bought our 2007 2701SS for just under 10k Canadian privately. It looks like it had low usage, but needed some minor repairs (door and baggage latches, and some awning pieces). The quality seems decent, but it's not a fancy trailer compared to what's out there. Your layout looks like it might be a bit better for full timing.
