As I read this forum, I guess I never thought I would see Davison Mi mentioned. This was the town I grew up in and graduated from High school in. (Class of 62) I can't give you an answer to your question, because I moved away in 1965 and the area you speak of was nothing but farm land at that time. A google map search of the area now shows many houses along thoses roads you mentioned in your post.The Davison area was always a nice area to live and I don't think that has changed much over the years. The only RV related information I can relay is that if you own a 5th wheel. the Hensley Air Ride Hitch is made there on M-15 south of town. Sorry I couldn't help, but Thanks for the memory.
