Look this question will start getting some very opinionated answers. My wife and I have been fortunate in business and could frankly buy any unit made, and even looked at custom options. Most responses your about to get will be people without direct knowledge just "hearsay", no direct knowledge, just telling you to buy the one they chose or what someone told them to buy! I selected a new 2012 Montana 3750. We liked the high ceilings, ( note not all as high in living room) we liked the way you can make a private room out of the living room and most important having two doors! We have owned ours for a year. Issues have been few, with exception of a slide material causing one slide to bind, but all problems were addressed timely, and without a question by Keystone. 9000 plus miles and it's solid as day we bought it. Ours has "every option" with exception of full body paint by choice. Montana's are full time constructed, have great value and have remarkable resale value. Pick what you like and can afford. Last pick a brand that has no limitation on where you have it serviced. Keystone dealers from Ca to New York have treated us like their own customer. We bought ours at RV Station in Tx. Best price we could find and they were willing to get options not on the regular order forms. Hope this helps !
