I was merely trying to distunguish between the kingpost truss in question and all other bents like queen post, and ones that do not clear span but have posts in king or queen positions. The kingpost is not unconventional per sae. Sorry for the poor word choice.
You are worrying way too much about the load carrying capacity of a king post. Stop worrying about it and calculate your load and then the size of the members in consequence!!
I agree totally! I'm working on it, trust me. Just reviewing my statics last night- method of sections and joints, sum of forces and moments equal to zero etc. Been bogged down with plumbing work at my mom's house and my own(farm house).
