Why have dual axles when a single axle will do the job.
Is this a need for heavy two placed sailplanes?
I know twin axles are beasts to wrestle when pushing it around unless
you want to go forwards and backwards.
Dual axles seem to be relatively popular in the UK.
Someone out there must have some explanation.

Typically Cobra or Comet trailers with a 15m or standard class ships
in them weigh about 2000 lbs. Alco axles come standard on the Cobras
and the axles are rated about 1000 kg (2200 lbs). Add the extra weight
of an open class ship and bigger trailer to accommodate and you're
probably pretty close to 1200-1500 kg therefore it takes one more
axle.
You can get a Cobra trailer with a single axle for a Duo Discus XLT.
There is a "Heavy duty axle" option on the price list.

I know a Nimbus 4DM weighs a lot more, but presumably the heavier axle
can handle this too.

I have given this some thought and the only advantage I can see with a
dual axle is that it would/might allow a smoother ride for the trailer
and contents through potholes etc. But at the cost of more vibration the
rest of the time.

No real justification for using a dual axle - there are so few
circumstances where it would be better.

Certainly my medium term plans include converting my current dual axle
trailer to single.
