We just ordered a 2017 Big Horn 3970RD about 3 weeks ago. For this model, the 2017s started being produced (with few changes) in the spring, March to April timeframe. However, the 2017.5 models with all the changes started with any units effective August 8th, so we will be getting the latest model that will be revealed at the annual dealer show in mid-September. We are pretty excited - new items include leg less dining table, all LED lighting, LED lightings in the slide facias, two new color combinations (used to be 3), new front cap logo, side access panel for access to rear of residential refrigerator, and many other changes. Should be here in the next 2-3 weeks.
