The "inflatable exhaust air jacks" work absolutely the best on uneven/sloped terrain and actually mold themselves perfectly between the vehicle and uneven ground like a giant pillow. The inflatable bags are pretty tough and durable as is, but additional protective liners like car-mats aid in puncture resistance. The inflatable air jacks absolutely excel in difficult recovery operations such as deep mud, where the wide footprint and high flotation of the air-bag is still able to lift the vehicle without submurging itself into the mud. In addition, the inflatable jack will not slip-off and lose its vehicle or ground contact point like a high-lift jack will. The inflatable exhaust jack is by far the safest and best jack to use in any off-road environment; it doesn't weigh squat, and it doesn't bounce around the truck interior causing possible damage or personal injury like a high-lift jack.
The high-lift jacks are the jacks that only work well on totally flat surfaces under perfect conditions. On unstable/sloped ground, the high-lift jack can easily slip-off the mounting point (ground contact point AND/OR vehicle contact point) when the added weight and stress is applied during the jacking process. When the resulting high-lift jack quickly pops out of place, it can immediately cause further vehicle damage, permanent injury or even death!!! The high-lift jacks are extremely dangerous when used in an unstabe off-road environment and are totally worthless in mud, as the jack will just bury itself deeper into the mud (wasted effort). The high-lift jack should only be used on a totally perfectly flat, non-muddy surface under the most ideal conditions. The high-lift jack is old world 20th Century technology, and has been replaced by the safer, more lightweight and durable state-of-the-art 21st Century exhaust air jack which has endless vehicle recovery capabilities.
