Hey Burt

That about sums it up.

There are different tools for different circumstances. Lots of parts of
South Africa where a breakdown could be quite hazardous.
Lots of generally excellent freeway where the speed limit is 120, the
cambers are designed for 120 - and the 18 wheelers will ride right over
you from behind if you don't keep up. On these roads the safest is to
have a combination that is comfortable and stable at 110-120kmh.

Where safe to do so - it is a lot less stress and danger driving a
little slower and exercising a little more care. Unfortunately it is not
always possible to avoid the heavy traffic. In South Africa again, many
of the secondary roads are in appalling condition, and take you through
endless informal settlements with high traffic density of animals, kids
and alcohol fuelled pedestrians. Best to stay on the main roads where
you can. In the UK you can get giddy from all the little roundabouts on
the B roads.

I find having an appropriate combination for the circumstances works
well. Investing in some comfort and safety makes it a lot more pleasant
getting there.

The day someone manages a 500km+ drive with a glider trailer attached
with a GPS average speed over 100km/h in the UK they should let us know.
