We have a 2013 Encounter 37TZ bought in Jan.. 2013 and it has been a headache. The customer service is very slow but there if you don't mind waiting. Sometimes it has been weeks.
The 37TZ has 3 slides and one is cable driven. It has been a nightmare for the whole time and I am not convinced it is fixed yet. The cockpit windows have been replaced but they still vibrate on a windy day. No fix it sight for that. We had a phantom water leak in the plumbing which no one ever did find for sure. It was sporadic enough that I cannot be sure that I fixed it yet.
I would not buy another Coachmen class A but maybe we just got a bad one.
