PhilD,
You are exactly right. There has always been 2 schools of thought when you encounter mud. High wheel spin or crawl. Alot of this depends on the vehicle and the tires, but with today's vehicles (Land Rovers, Land Cruisers, etc) nearly any obstacle requires low speed crawling. These vehicles with the traction control properties are not made to "throw alot of mud" and do their best when you are at low speeds when off road.
The picture above is a result of getting stuck and then making matters worse by "trying" the high rpm wheel spin. The whole frame ended up on the ground and the right tubelar assist steps was bent up and back about 3 inches. The rig could not simply be winched out without using a few snatch blocks and several hours. Over 3 tons dug into the ground creates alot of resistance. By the way, even though the whole frame was dug into the ground, there was no damage (except for the nerf bar) and cleaning under there was not a big deal.
