How to price a TT that has been lived in for 5 years?

Wouldn't even consider it. There are a lot of lightly used travel trailers available. six years old, full timers, two owners and large animals wouldn't even be on the radar. Our trailer was six years old when we bought it and had never been slept in. They are out there. I would sacrifice floor plan preference to get a mint condition trailer. $18k also doesn't sound like such a great deal.
