Even glider trailers can differ markedly from one another, so it's no
stretch to imagine caravans (less than half the length, 30% wider, and
twice as tall as a glider trailer of the same weight) might act very
differently behind the same tow vehicle.

One of the findings I remember from the Bath University study was that
aerodynamics had little effect on stability - it was all about weight
distribution. Shame the research is "pre-internet" - though maybe it
got published in some engineering journal somewhere.

However it doesn't really matter what shape, size or weight your
trailer is, the basic rules always apply. You could never recommend
having a negative noseweight or towing with a vehicle lighter than the
trailer, for example.
