I don't think that would work. The specs for the trailer mattress say it is 78 X 78. If I am correct, the king size mattress you have at home is 78 X 80. Also, there is not enough space for the thickness of an innerspring matters. You would not be able to close the TM down. One option might be a mattress such as "Sleep number" which could be deflated for closing and inflated to your desired firmness.
On a personal note, I found the standard mattress in the TM to be much more firm than I wanted, so I added an egg crate on top of the mattress for more softness.
