I'm considering buying a new four wheeled, CDE type carriage from Frontier called a Traverse. I plan to order the team pole and drive a pair of minis. Does anyone have any experience with that? What modifications will I want to make to it? My husband is a welder and really handy in the shop. Does it come with the two single trees, or a double tree, as well? What about the brakes? They say they are to stabilize the carriage on a hill, but not stop a horse. How good are the brakes? Has anyone upgraded them? How about the suspension? Any need to upgrade that?
