Foretravel is in a top tier above the others you listed. Newmar and Entegra fall into a category below that but above the crowd. The hung wall and heavy cap and wall insulation is in my opinion superior to the laminated wall and minimum / no insulation in the caps of tiffin and Winnebago. I would put winny and tiffin together in the same level and imo after seeing most build tours slightly lower than Newmar or Entegra Others would disagree of course.
Entegra has a lot of models and good used resale prices make them a good buy , side radiators , Agua hot ,lots of other pluses !! Go to the Entegra forum .. I don't think anybody is "dumping" them but many are trading their aspire for a anthem / cornerstone move up. Seems to be a large base of buyers that have the ability $$$$$$$ to trade annualy or every few years I believe 150 grand will buy a very nice late model 5-6 year old model .. not so much on the Foretravel way to expensive. Unless you go 10 years + out
Newmar and Entegra are on our short list for replacement of our current coach.
