Welcome aboard! Depending on how deep that truck was under, you may be in for one hell of an experience. I flooded my 89 half way up the doors once when I got stuck and had to leave it overnight. The river came up so fast that when we went back it was up to one the mirrors. I replaced the manual transmission, had to rebuild the rear end, and had electrical problems (gremlins) forever! Lots of money and time and it's finally past it all..
