We have a 2007 Montana we bought new July 2007. Could not be more pleased with it. There is a very active Montana Owners Club (MOC) forum with lots of full timers who are very happy with theirs in all types of climates. Of course, there are also some who have had problems to varying degrees. I think they are as good as any in the price range.
You need to check weight ratings of the trucks carefully. Truck payload ratings have really gone up a lot over the last number of years. I would definitely recommend a 350/3500. The pin weight of the trailer would determine if you can get by with a SRW, or if you need to go with a DRW.
