We have a 2012 Sunseeker 3170, have put 18,000 miles on it, and have found it to be well made. The Forester is an upgraded Sunseeker with upscale finishes. Mechanically they are the same. The Forest River forums, which are second to none, have forums for both Forester and Sunseeker. I suggest you take a look there and look at the RVs themselves before drawing any conclusions. I would not trade our Sunseeker for a Winnebago; others may disagree. If you have kids or grandkids, look at the kids zone in the 3170 and the Forester 3171.
