You need to get the inside dry and then get a water hose and go over the car section by section and check for leaks. If the truck has water in it pull out the carpet and spare, then get rid of the water with a shop vac or by pulling out the drain plugs. Then hose down the trunk and check for leaks around the taillights, the trunk lid seal and the rear window seal. For the interior if you have mold you need to pull the carpet up, pull the drain plugs or vacuum out the water and then see where it's coming from. Common leak points are the door and windshield seals, leaking AC drain line, leaking heater core, and clogged body drain lines.
