We have three Monty dealers in the area. Lloyd Bridges Traveland in Chelsea (about 30 miles west of Detroit) and they go to most of the shows. This is the dealer we purchased our Montana from
www.lloydbridgestraveland.com 800-475-1347. We were at Lloyd Bridges about a month ago and they had no info on the Cambridge at that time. A&S RV Center is in the Auburn Hills area
www.asrvcenter.com 248-373-5811 no toll free # listed. There is another dealer in Marlette that just started carrying the Montana but they are quite far away and I don't think they participate in the shows. Hope this helps.
