Some of the bullet points in the 10 Don't I fully agree with, but only because it corresponds with physics and common sense.
So break it down. It will only add to the discussion. My personal experience has shaped my personal opinion which is always related to bias. You say that you do not fully agree with the bullet point - cool. Lets see the specific 'physics' that are flawed or the 'common sense' that is being questioned. We will all be better for it. I am not trying to be argumentative, I am genuinely interested in your thoughts.
#8 is a contentious one as CBs are currently prolific in the US. It is like any technology, there is contant innovation and movement. In my opinion, the benefit of the CB is cost (i.e. cheap) and popularity in North America. Functionally, it is flawed by the nature of it being a citizens band. The nature of this site is backcountry travel, exploration, etc., which results in long distances, remote locations and potentially significant spacing between vehicles (dust). A HAM radio is simply better IMHO. With a little more money (2M radios can be obtained relatively cheap, even $100) and some time (HAM license) you have a superior communications tool. The 2M radio in my Discovery is 80Watts. That is 20x more powerful than a CB (legally).
It takes some time, but people are converting over and finding the communications so much less frustrating and more effective. We can talk 20 or more miles apart. In cities, we can communicate easily. We all started moving this way with the encouragement of Jack from 4wdTrips. He was right - it was worth the effort.
I suppose my point is 'best practice'. Something that is cheaper or easier is not necessarily a best practice, it is just cheaper and easier. It is best practice to run your vehicle under GVWR.
