As others have said "file an insurance claim" then get a local disaster clean-up company in to the MH. Good chance that all the carpet will have to come up (if not repaced)and for sure you will want to replace the padding. The Pro company can run tests for mold in the walls and othe locations. The nice thing is that the disaster clean-up companies work hand in hand with the insuance companies and can tell you exactly what they will and will not pay for
I flooded in my house 2 years ago (fire sprinkling system in ceailing broke) but got a disaster company on it right away. Cost over 100,000 to fix but never did the insurance company question the Disaster clean-up companies bills.
