The Springdale from Keystone is a family of lower-priced trailers. Probably as good as any in its price class, but you aren't talking top-of-the-line models. The construction will be driven more by low cost targets than high quality and long life. I'm not bad-mouthing the Springdale - just trying to set your expectations. Expect lesser quality upholstery and cabinetry, fairly rough construction behind the visible areas, relatively light duty trailer frame, etc. I know a couple who have one and they get decent service from theirs, but they basically use it for a 2-3 week trip twice a year.
In the Keystone product line-up, the better built models are the Bullet, Premier, Outback & Passport. Naturally, those are all higher priced models.
