It would have been a good idea to get out on foot and examine the condition of the soil before attempting to cross with the heavy VX.

Contrary to Peanut Butter Kid's advice; your scenario of being stuck in the mud is a prime example of why a "high-lift" jack would be absolutely worthless, as the high-lift jack would simply bury itself deeper into the mud immediately upon jacking. The very best jack used for muddy situations is the famous "Inflatable Exhaust Air-Jack" that has high flotation capability and a wide footprint enabling it to still lift up the vehicle. A simple "come-a-long" can be used in lieu of a winch.
