I have a fairly new mobile home.(4 years old) I am interested in installing a gun safe (575lbs) and centering it directly on the I beam which has the leveling concrete block tower directly underneath were I would put the safe. Would I need additional support for the floor? I don't want to have to rip the belly rap up to build additional support. But I can and will if needed. The moblile home is a Chandeleur 16x80.
