I don't have the warranty info at hand either since I'm in the rv park office at the moment but the others are correct. The primary Montana warranty is one year with other things being longer, like the roof. Thing like the fridge, water heater, tires, etc., are warranted by their respective manufacturers. Montana dealers usually take care of these things or help get appts if needed.
We're on our second Montana and fourth fifthwheel. The first Montana was a new 2001 model we kept for 18 months. We had an initial problem of the rear brakes not working at all, just the front axle brakes. That pretty well wore out the brakes on that one axle while the other axle's brakes were never in use, they were still brand new. When the dealer discovered this problem after about 6 months of ownership, Keystone told him not to replace just the worn out brakes on that axle but to replace all four from the backing plate out to make sure we have consistent braking all the way around. That impressed me a lot.
When we decided to fulltime we traded for another new, 2003, Montana so we could have a washer and dryer in it. We've had only minor problems with this one. Nothing major at all. We've towed it all over this country, to both coasts twice, and currently are in WV, in the past 17 months. You can see just where by clicking on the link in my signature. We have very, very pleased with the way this Montana has held up. I can tell you right now that if we were to trade again it would be another new Montana. Well, if we won a megabuck lottery we might go for a custom $100k plus rig
but otherwise it would be a Montana.
Montana has been the number one seller in North America for three years in a row. There surely must be a reason for that.
Hope this helps answer your questions. I don't mean to make it sound like Montanas never has problems - that just isn't true. They're mechanical and we bounce them around on rough roads, etc. But Montanas seem to be well-built and Keystone sure is good about standing behind them.
As Lightningjack11 mentioned about his, some of the early Montanas had a smaller frame that turned out to be a problem. I believe 2000 models were the newest I've heard involved in this. To this day Keystone is fixing these units even though long out of warranty and owned by second and third owners and they're doing it at no charge. Now that's a great company. You can find posts in this forum from folks who have had this work done and feel the result is at least as strong as the newer models, maybe more.
Gee, I sound like I work for Keystone, which I don't. But I am very pleased at how they've treated their customers. Good luck whatever your decision.
