Well, you're probably out of your warranty & grace period.
I'm guessing (educated) that the soft spots are starting right where 2 pieces of underlayment are coming together. I've tried floor leveling compound to solve this, it doesn't work - no flexibility. Ended up replacing the floor. It might be a major repair, but try removing the linoleum, liquid nailing down some 1/4" underlayment, and installing new vinyl over the top. When you install the new subfloor, make sure you don't put the joints over the existing joints.
Scenario two: your lamination glue is letting go. It's going to get worse before it gets better. Your floor structure is gradually breaking down. The camper will last a very long time, you'll just have a bit of a squishy floor.
Scenario three: double check your frame cross members. Add more, if necessary.
