Sorry to hear you're in this situation. It all depends on how high the water got. You will have to try and find some sort of high water line or evidence when you return to it. If it got no higher than the rockers then I'm sure it will start ok, but I would not drive it very far without doing some 'repairs'. I would recommend draining and replacing all the fluids. Diffs, transfer case, transmission, engine oil and brake fluid. If the engine got completely submerged, then obviously do not attempt start it until you're sure all the water is out, especially from the cylinders. The easiest way to do that is by removing the spark plugs and turning the engine over so any water in there gets pumped out. Unfortunately, I suspect damage to electrical equipment will be a problem too. Good luck.
