FWIW, my bestfriend years ago was "driving around" (long story short) and went though a frozen lake a swim and a sprint he calls me, I circle the wagons. The truck, about 40y from shore, on sandy bottom, I would say depth at 15-20'. Lots of manpower, chainsaws, axes, chain, and adreneline! We cut a pathway though the ice and into pieces, my friend agian-went for a swim (we now had a large bonfire) to set the hook! My (then) 1ton locked 44's and 10,000lb. winch started the pull with a block, it pulled my truck about 5' in the sand before I anchored to 2 other rigs and out it came! GO SLOW, I repeat GO SLOW, this is NOT the time to be in a hurry.
His rig was a '79 Ford 1/2T PU on 39's, so, it can be done. I will say, and as others have- the current would scare the $h!t outta me! As a fisherman, I know rivers, when a river looks lazy-its not! its still moving the same amount of water.
Oh and BTW he rebuilt his truck, PLEASE DO be carefull, and next time- extend you breathers and get a snorkle- those things are not just for malls!
