Some trailers will drain where the floor meets the walls, check all compartments under the trailer skirt and if they are wet clean out and air dry as much as possible, also open all floor cabinets and drawers to check for dampness, the vinyl floor may turn up at the edges and corners, otherwise if you are not living in it put a heater on, not the cabin heater, that creates too much humidity, that is what you are trying to eliminate.
On the carpet rent a carpet cleaner to suck the moisture out of the carpet or use a dry-wet vac for this.
Good luck, it is not too bad, it did not sit in a river full of silt and who knows what for several days.
