Cougar floor bubbles

[Howie]

I have a 2015 Cougar 303RLS that has developed warped flooring and is just the floor covering not the subfloor. There is a slide that the slide roller sits on about the same line as where the bubble developed in the middle of the floor so it may be part of the problem but not sure. I removed the vent you can see in the picture and the flooring is not glued down in the area where it has lifted. Maybe the summer heat in Las Vegas is part of the reason it expanded. The obvious solution would be if there was a seam that I could trim and reset but the flooring is one piece all across the area. Anybody has a solution as to how to flatten it out again?

I attached a picture that shows the vent and the area on 3 sides past it is not warped. The area between the vent and the cabinet shows the warping

Does the linoleum lay flat if you press on it with your hands? I have had some success heating with a heat gun until it was “soft” and then putting a gp27 battery on it until it cooled.

it will lay flat if you press on it. I will give it a try next time I get it out of storage. I hadn't thought of using heat as I was thinking that would make it expand more. Worth a try. Thanks
