Here's my first Pine Barrens exploring truck - a 1986 Grand Wagoneer. I owned it sometime in 1998. Sorry for the dusty scan.
I killed it by driving through a large puddle on either Hawkin's Bridge or Godfrey's Bridge road. The air intake was a hose that ran right from the carb to the front grill, and the motor swallowed a decent amount of water. Not enough to hydrolock the engine, but enough to make it burn a lot of oil.
That's why, even with more experience and more capable off-road vehicles, I am super paranoid about going into/through puddles.
