New guy with questions- 2012 Montana Big Sky

[Columbo]

Hi, I’m new here and looking at my first fifth wheel (no previous RV experience). My wife and I (and our dog) are looking at purchasing this trailer to live in between the sale of our current home and the completion of our new home. We anticipate living in the RV for 18-24 months. It will be parked on a site near our new home with hookups for power, water, and septic. Since this will be home, we are looking for a model with ample space and storage. Additionally, I’ve been reading about how to prep these units for winter living, but I want to start out as far ahead as possible with a unit that is as “winter ready” from the factory as possible.

After looking at several RV’s for sale nearby we have narrowed it down to a 2012 Montana Big Sky 3625RE. It looks to be in excellent condition, very clean and has had regular maintenance. Any specific areas to check on this model? Are there concerns about a unit of this age if it’s been maintained? Finally, the owner states that this is a full four season model but I didn’t see the four season badging near the door, are the 2012 models fully insulated/heated for “winter” use? Thanks in advance!
