I like Jayco's I-Beam frame, plywood floors and roof. After having my 2016 for a few weeks now I am NOT impressed with their cabinetry whatsoever. The shelves are paper thin, glued joints are messy and the methods in which the cabinets are constructed are very poor.
For example, I just spent a week at my friends house in California. He let me stay in his 2012 Dutchmen trailer. All the cabinets were double wall construction so none of the attachment cleats were visible. The outside corners all had 1/2" radius edges and the shelves were all double wall construction too. Everything about the cabinets in his trailer were far superior to my Jayflight. But his frame, floor and roof structure are not very well designed. If you want the best of both worlds I would spend the extra coin and buy a Nash, Arctic Fox or Outdoors RV. They are in another class altogether.
