1st, congratulations on your new Montana and welcome to the forum! We love our 3150RL.
I'm not a big fan of extended warranties. You need to read the fine print VERY carefully. There are a lot of horror stories about people stuck on the road needing to get something fixed and can't contact the warranty company to "authorize" it so they get it repaired figuring it's covered under warranty only to have the claim denied because the warranty company didn't authorize it 1st (see issues of Good Sams members magazine) I'd rather sock away that money in a "what if" fund and use it if it becomes necessary. In my experience, most issues manifest themselves in the 1st year anyway. Your paperwork (title, bill of sale, etc.) will tell you if your rig is a 2011 model year. Keystone always labels their units 1 year in advance so something that is built in 2010 is marketed as a 2011 (I know it's confusing).
