It has been suggested by some contributors that unless there is a fully tested and proven alternative, then its wrong to question the industries present advice. Are these people really wishing to prevent sensible discussion about a subject that is controversial becasue it challenges a long held tradition?
I haven't seen any posts which prevent you from discussing the 85% recommendation Prof.
Personally speaking I'm slightly curious about the apparent long held fixation on this one facet of generally accepted towing ratio wisdom, but if endless and ultimately fruitless debate about the 85% recommendation keeps you happy please continue, nobody can stop you as long as you avoid hijacking other threads.
I've seen this debate continue over several years with no apparent conclusions, it has continued to go in circles on this thread, just as we've become accustomed to over the years.
I must admit to a passing interest in what alternative advice should replace the 85% recommendation, but from what I've seen over the years the same old ground is covered with the advice being challenged, often with misleading assertions about the advice being suggested as a stand alone facet of towing when in fact that is far from the case and with no logical conclusion or result.
I have reinforced the 85% recommendation on this thread, simply to avoid any novice caravanner reading the various assertions and theories and being more confused than ever.
You are quite welcome to continue with your discussions which challenge the received wisdom that currently exists, but you can hardly expect your own challenge to pass without comments contrary to your line of thought, it's nothing personal.
It's fine to question the boundaries of accepted practice, but it's unrealistic for anyone to theorise within the public arena without their theories being challenged.
