Just ordered our Gen 3 a couple of days ago from Tow Universe as they seem to have the best package deals around. If your pin box wing spacing is 12 1/2" inside to inside, you will need the spacer adapters as the Goosebox itself is 12" wide.
Being an old country boy, I'm looking forward to going back to a gooseneck ball. Fun part will be teaching the DW, but there are some tricks to make hitching up easier. Lots of YouTube videos for the less experienced. Good luck with your decision and happy camping!
