What year is your camper?
I have a 2013 Jayco Whitehawk 28DSBH and I have the soft floor issue pretty bad. I purchased the camper from a friend who had it for 2 years. It had a small soft spot in it 2' inside the door and a small dent in the floor where something heavy fell out of the freezer and dented the floor. Other than that it had no issues. That was March of 2019 when I purchased it from a friend. The soft spot grew a little last year, but this year it has grown bigger with each of our 8 trips (~22 nights total). Now the floor is soft from about 6" inside the front door up towards the slide, then down the middle of the camper to spot near the fridge. It is concentrated to the middle of the camper and it 12-18" wide. The rest of the floor seems fine. I am so upset and not sure how to fix this. Does anyone have any references, suggestions or ideas of how to fix this?
