I generally don't recommend a come along or hi-lift jack. Most drivers are not capable of using them safely. Ratchet straps come in handy to hold a bumper on in order to get home after a minor accident. Also, I've seen deer strikes break the latch on a hood and make an otherwise drivable vehicle undrivable. Ratchet straps help out in many different types of minor accidents and can obviously also be used to properly secure a load in the truck, bed, or roof of a car. I partial to using a hi-lift jack with chains rather than a come along. High lift jacks are also useful for removing fence posts and moving fallen debris when combined with a sturdy chain. However, both of these tools can be extremely dangerous.
