Some Random Notes:
1) Looks like Rebel loses Trailer Tow Group. All options (trailer tow mirrors and brake controller now ordered a la carte)
2) No new color options across all trims
3) Can't get Power-Folding Trailer Tow Mirrors on Big Horn (this might be a mistake, as I don't see why Ram would omit them from their most popular trim)
4) Technology Group available across all trims (except Tradesman)
Last but not least, and most important, Ram hasn't officially released this information yet, so there are bound to be changes.
