I found asking around friends, coworkers etc can pay off. My first TT was a 2002 Layton skyline that was in immaculate shape only two owners and had no issues. Found it though a coworkers camping buddy in conversation one day. The guy sold it to me for 5000 with a cover, all accessories, weight dist. bars, sway bars, etc. Used it for three years and ended up selling it a few months back to another couple that wanted to try out TT camping. Point of story is sometimes just mentioning to people your looking for a TT for a good price can open doors to the perfect solution.
Good luck on the hunt!
