If your anything over about 6'2, your gonna be hitting your head on the ceiling of most bumper pulls. I'm 6'4 and the only ones I ever fit in were pretty much brand new (and expensive).
Like has been mentioned, hunt CL if you want one. People buy them and cant afford them or there's the older crowd who buy 1 brand new, gently use it for a few weeks maybe a season, and its too much for them or they don't feel like taking care of them. You can find them almost new for good prices a dime a dozen in FL, probably in your neck of the woods too. There is definitely deals to be had. 5th wheels are the way to go, I got a 2007 31ft for $13,900 in January of 2013. The guy still owed $24,000 on it and it was $40k new and still looked brand new.
Coachman & Forest River are good brands for sure, been around a while.
If there's even a remote possibility of using it in less then 40° weather, for sure for sure get a 4 season (extra insulation) unit too. I learned the fun way..
