Help finding a Lance camper for sale

Where can I look for a nice newer used Lance camper for sale by owner.
On RVTrader it's almost all dealers and the only other source I have found is Craigslist.com
I am located in Phoenix Arizona.
I would really like a 2013 or newer for the front cap but a bit older would also be okay.
Need a camper for a long bed 3500 Dually but don't want a 11 series as there just to big for me.
Any advise is really appreciated.
Thanks
Dan
