Mr. Rawles,
I just purchased the Kindle version of “Survivors” and can’t wait to start! But that’s not what I’m writing about. There’s a very interesting video titled Kelly McCann’s Crucible High-Risk Environment Training Volume Four: Mission-Essential Off-Road Driving
The video starts off by explaining the various setups you may find on commercially available SUVs (solid axle versus independent suspension, traction lockers, et. al.), and the type of gear that one should have for recovering a vehicle that gets stuck off-road. The then get into the nuts and bolts of negotiating terrain without getting stuck or damaging your vehicle, and how to recover a vehicle that has become stuck. In all, I found the video very informative, and I believe it has a good deal of information that would prove useful to your readers as well.
There’s much more content than my little description here can convey, but you get the gist. The material is presented by former Marines who’ve operated overseas, both with the military and as private contractors, and they convey their information in a straightforward manner, warts and all; their conversation is laced with casual profanity and repetitive expressions (“bottom line” in particular) but the information is top notch.
Also of note, is that you’d rather “rent before you buy”, then Gold Star Video has pretty much the complete Kelly McCann/Jim Grover combatives library. They function something like Netflix for martial arts videos, with the option to purchase if you like them. Many of us are on a limited budget, and their service allows you to rent a video series for a month at $9.99 per video to give them a “test run” before purchasing. Definitely worth a look, at least.
