IMO a used 2009-2011 is a better buy than post-recession 2012+ models... The Recession hit the RV industry hard & IMO the folks that still had jobs were the best/most experienced & willing to work harder to keep their jobs...
Last year when we were looking at new 2014 TT's both FR & Thor/Keystone products looked rushed off the line... A Keystone TT we liked had sawdust & wood scraps everywhere combined with poor fit & finish. A new FR PrimeTime Tracer, same as ours, was leaking water badly during a heavy storm. In comparison, our used 2011 was bone-dry & not a single trace of sawdust behind access panels. Either the previous owner took time to clean back there himself, or it arrived from the factory in pristine condition. IMO it looked like it was built right.
We've owned our (used 2011 ) TT for just over a year & after 30+ days of camping did not have a single problem. Before the PDI the dealer adjusted the slides, awning and did a free pressure test/ re-caulking. During the PDI they replaced the CO2 detector, battery & filled the propane tanks. We're very happy we chose this 2011 vs. the 2014 that was leaking. I'll bet the folks who bought that one made a lot of trips back to the dealer their 1st year...
