front axle actuator on chevy's is known to disengage in cold water, after the first few seconds he was stuck in 4wd. Doesnt mean he would make it out in 4wd anyway, the driver looks clueless.
Okay, but how about neither of these drivers are the best, but the Jeep has the advantage. The Jeep is what you buy for dedicated off roading. Climbing, mud, crawling, etc. The Tahoe is what you buy for towing and trail riding. The older ones were better for doing jeep things, but the Tahoe looks pretty bare bones in this video. Give the Tahoe a little suspension upgrade, some good tires, and a competent driver. Suddenly, it's not so bad.
