I was considering a Challenger 37LX, but ended up purchasing a 2014 Hurricane 34E instead, (a deal I just couldn't pass up).
I like the features of the Challenger that qualify it as 2 steps up from the "entry level" Hurricane/Windsport, (after the Miramar line). The basement access door styling, the 22.5 wheels, residential refrigerator, and the larger capacity tanks.
I have had a great time enjoying my Thor product this past year.
