The "Polar Vortex" ate my 5th wheel floor!! What to do?

Well after 7 winters outside, this last week caused my vinyl floor in the 5th wheeler to crack right down the center. We pride ourselves on the appearance of the trailer and this really hurts. Has anyone in cold regions of the country experienced a major failure with OEM vinyl flooring? If so what did you do for repairs? I was wondering about vinyl floor boards but I wonder how this would handle some extreme cold temps?

Any ideas or suggestions would be appreciated.
