Have you noticed how the boxes on new trailers are
now square


If we're talking Cobra, isn't it just metal top - square,
grp top - curvy?


The latest square finbox I saw was on a GRP top.


I have a trailer that happily tows at 80mph and has behind a number of
tow vehicles. *I am currently towing with a short wheelbase Volvo
SUV. *This trailer is uniquely low, but seems to self damp when a semi
passes or the wind gusts and has an aerodynamic fin. *I have always
suspected it has something to do with the fin to trailer wheel moment
vs trailer wheel to hitch moment. *I have never had to play with
weights etc. *The wheel placement is different than the Cobras which
seem to be more centered.

How much does the trailer and glider weigh? I suspect it's quite light,
as the forward wheel placement generally works against stability. I'm
reminded of a couple trailers Roger Frank built years ago.
