I have a 2014 Alpine 3600RS 39 ft. Both Alpine and Montana are rated equally as luxury 5th wheel units by Keystone. In my opinion they are comparable in quality and features. It is a little wider than the Montana. I am planning on selling my unit later this summer so I can purchase a Montana 3791RD only because I like the newer layout and features. The advantage of the Alpine is that it costs a little less and you get many of the optional Montana features as standard equipment. i have had virtually no issues with the Alpine and I think either unit is great and it's a matter of personal preference. Did I mention that my Alpine may be available?
