Montana High Country Floor Construction Question

Reading the brochure for the 2018, then the 2019 High Country, it looks like Keystone changed from using the foam sandwich floor in 2018 and earlier to using the 5/8" dynaspan OSB one piece floor starting in 2019.

My question is, was this done at the start of the model year in 2019, or was this a "mid year" change?

Do ALL 2019 Montana High Country have the one piece Dynaspan OSB floor?

Thank you everyone for your help.

Welcome to the MOC. Can't answer your question. Been looking on YouTube.

I'm curious about this as well. Our 2018 has the foam sandwich. It's a solid feeling floor but would prefer the 5/8" plywood floor for better strength. The full Monty has the 5/8" floor, but the HC has had the foam floor to save weight.

Tony, if you have the time you can pull the basement wall in yours and look where the plumbing goes into the underbelly to see which type of floor you have. That's the only place I know where you can get a good look at it.

Although I'm not super familiar with the newer ones but with the older ones if you have heat ducts in the floor simply remove one and you can see the makeup of the floor

My rig is at the dealership. I'm getting my driveway worked on so I took it there for storage lol. Told them to test the fridge cooling unit. As soon as I pick it up next week I'll take a look the the sub floor.
