The next day I checked things out (after hunting all morning, of course). Both dipsticks looked perfect, battery voltages fine, but the engine wouldn't crank. I bridged the batteries together and pounded on the starter. Finally it turned, but wouldn't engage. I turned the engine a bit by hand and all was well, so I pulled the starter off. After hanging near the woodstove for a bit, water started running out of it. After the dripping slowed, I bolted it back on and the truck fired right up. Every U-joint was frozen, but with a little gas each gave its own "BANG" until I was rolling. Other than a noisy alternator bearing, everything seemed OK.
I gave up on any more hunting and headed out the following morning. It's hard to find parts on a Sunday (in the UP), but at least I would have time to deal with some stuff. The power steering pump was now really noisy and the fluid looked a little...well...brown. But I was rolling...
What you can't see in the pictures is that the bottom of the grill broke....from the ice. I had pulled 2" thick sheets of ice off the front axle after getting out of the hole. The whole thing must have been a sheet of that before I broke through.
I couldn't unlock the hubs when I reached pavement because the dials were like little ice-cubes. I couldn't find change for the car wash, but the drive to town thawed them enough to move. Good thing because my front driveshaft was vibing like crazy. I got to do some parking lot power steering flush using soda bottles, too. I could have headed West towards Escanaba to find a pump and an alternator, but it's a 1987 Corvette case alt. And the pump is for a TPI Camaro, pressed into a reservoir modified with a second return line (for the hydroboost brakes). So I might not find stuff anyway, didn't feel like messing with that pump and everything was working. So I just headed for home, drove and drove and everything was fine.
I made my flight out Monday morning, but didn't get to de-water the truck. Rear diff looked fine, front diff was questionable. Was gone all week.
The next weekend I drained the front diff. It didn't look milky or wet, just dirty. There's not a lot of use on that oil, so I assume it's a touch of pollution. Still need to look at the winch, front hubs and T-case. The vent lines for the axles, T-case and tranny are pulled up high near the cowl, but you can't count on seals working perfectly. It's hard to believe the winch didn't fill completely with water. It will be torn down in the next couple of days. Fortunately the solenoids are mounted high and dry on the core support.
