Our Montana Mountaineer 342PHT was not our first choice but it was the best purchase for the buck. If you look at
http://www.keystone-mountaineer.com/ they explain that the mountaineer is an upgrade to the Montana. We purchased our Mountaineer because it has a different floor plan then what was offered in the Montana. Geared more towards a family! Here are some pictures or ours
http://home.comcast.net/~brandtcpc/Camping.html as you can see it has a special floor plan that has fold down bunks in the back along with a bumper that slides out to become a bike rack alone with the extra high cabinets and upgraded counter top.
