A lot of people ignore this rule when towing because they have never had a bad experience and want to have the biggest trailer that they can physically tow.
Who wrote this rule?
If it were appropriate, would it not obviate the figure from which you subtract?
What then happened to the 40% rule for trailer brakes
which makes facetious assumptions about TV brake engineering, which are then used to write laws in some states.
Your "basic rule" clearly advises distrust of the manufacturer's rating, which is supposedly seen as authoritative.
Your comment then brings into question the judgement of those who would not follow a "basic rule" from an anonymous (or at least amorphous) source, which in turn is based on the assumption of bad manufacturer data. These are the very things which are supposed to preclude common sense and good judgement in favor of authoritative figures.
Now, if all manufacturers are assumed to be consistently wrong on the high side by 20%, what error factor should we then assign to the author of the rule?
Of course our own common sense and judgement having been already called into question, we are left with a choice...
Face danger or stay home!
Of course that presumes home is a safe place to stay?
Lord willing...I'll see you in Sebring!
