2017 forest river wildwood 28Dbud questions

Hello all, my wife and I are looking to buy our first camper, I have been looking at travel trailers no longer than about 30 feet. I have been looking at the forest river wildwood 28dbud but have heard some bad things about forest river campers as far as the screws they use on the outside rusting within 6 months. Also that some models had problems with the slide outs falling completely off the camper due to not having stops. Has anyone heard of these problems? Thank you
