I'm iike the ones that have (front flanges) on them that would sit onto of the tailgate.
General Safety pratices for me was to at least ratchet wrap that flange tight against the tailgate.
What I don't like is that most of the folding ones are somewhat short. Loner - shorter angle of approach seems more safe but I suppose they make it that way so it's more *universal* and fits in more cabs.
Are there specific *BRANDS* that are better than others.
For example, on multifunction ladders, I swear by the Little Giants. Built like a tank, WELDS are good, etc.
