Have to say that taking 7 minutes to make his point is a tad long but .....................!
It goes to show that even experienced towers can make mistakes. The only mistake I have so far made with hitching was actually on unhitching - forgot to remove the breakaway cable and drove away from the van. No harm done (I was at home) and a new cable has been installed (plus a spare now carried).
I always do the jockey wheel lift - it was shown to me by the place I bought the van from and is a routine part of hitching up. Another tip I learned - do not multi-task when hitching up; it's too easy to get distracted by something else and then miss a step in the hitch process. Rather like an aircraft cockpit you need a sterile environment during critical times - if the checklist gets interrupted, start from the beginning.
