A soft spot can also be a cracked piece of plywood. My current MH has what feels like a soft spot right next to the floor vent. After inspecting through the vent you can see and feel the crack from inside the duct.
Also some floors aren't supported well which will result in a soft feeling floor.
Ditto. We have a little "bounce" near a floor vent in the main entry way...which by the way is a goofy place to put one, IMO.
Several mfgrs have moved away from this (or never have) and place them vertically in panels throughout...best, IMO.
