Consider drilling a hole in each corner or at least in a couple of known low spots. leave them open for drains. Is the wood floor in your Little Joe
encapsulated? (fiberglassed over on the inside) If not you can air it out after draining to get it dry. If you have A/C, it will help to run it for a few hours to help dry it out since A/C acts as a dehumidifier.
Get it dry and be sure it is completely dry by opening all cabinets and removing cushions etc. to expose as much floor as possible while drying.
Water can cause a lot of damage and invites mold and rot.
You could open all windows
and doors and run a heater blowing into the recesses.
Don't forget that the windows have drains which must be cleaned and kept open which is much more likely a source for a leak than a bad window seal.
Another source for water is condensation forming on the inside, especially on cool nights when a heater is run inside of a closed camper. Always keep the roof vent open a little when using a heater.
