Why the Good Deals on Integra Qwest?

I had an Entegra Anthem and pretty much all their coaches are priced below comparable RV from other manufacturers, they are extremely well built, with 4things like solid wood cabinets and doors,the best insulation of all rv's.The only reason I can thing of is they don't do any customization and very few options. Pretty much what they have is what you get, keeping inventory costs low. Also they give a 2 year warranty and have excellent support.
