I have a 2015 Montana and I am in the process of having a new roof put on because of poor workmanship from the factory and they will not pay any of the cost, The rubber roof started coming loose from the membrane,They say this is not a manufacturer defect, I have had other issues with this trailer as well,Unit is 13 months old,So I would say go with anything other than a Montana,Read the Montana Forums,There is a lot of problems with the Montana roof and Keystone does not want to stand behind their product. Hope this helps you in making your decision.
