2005 fleewood mallard

Model years for travel trailers run a year ahead. The 2019 models are coming out now. That trailer is close to, if not past, it's 14th birthday. At that age, whatever name is on it, has nothing to do with it's condition, reliability, or longevity. It's all about how well it has been maintained.

More important question you should be asking is, what to look for on a used travel trailer.

Signs of leaks?
Evidence of past repairs?
Proof of wheel bearing maintenance?
Tire age and condition?
Full systems check?
Condition of existing caulking?
Frame rust?
