soft spot not getting bigger, concern?

Wow....Well first the camper you found online, yes that is what we have. The cargo hold in front, I thought that it was the weather stripping around the door, fixed that, recaulked all around the hatch and every other thing in the door of the hatch, next we went up on the roof and redid the caulking at the top seam. The cargo hatch is completely dry, has been all summer. As for the camper itself, we have never noticed any leaks around the entry door. We did find some small holes in the caulking on the roof around the front and rear seam and also around the TV antenna. Recaulked all of that, there is absolutely no smell inside the camper, in fact, ever since the recaulking we have noticed a rather pleasant non smell if that makes any sense. We also put a few containers of the RidX moisture absorbers in and they show very little if any moisture in them. We have been storing the camper beside the house this past summer, it sits on concrete but is not covered and we have kept the vents and windows ever so slightly cracked, just enough to let air in but no water. Freezing is not an issue since we are in Florida. It does get kinda cold in the panhandle for a few nights in January and maybe even February but when it does, we plug the camper in and have the furnace set to 40 degrees. Like I say, I really feel good about no more leaks. The soft spots have not gotten any bigger all summer but I was wondering if I should even worry about them.

Thanks for all of the help so far, I appreciate it.
