A couple of points:

Some years ago International Alloys in Aylesbury sent tanker loads of molten aluminium to their plant in Birmingham, a journey of about 75 miles.
I have a vague recollection that the load would lose 1 deg F for every mile travelled.
I assume that the tank was exceptionally well insulated and that some form of heating was involved, but the consequences of an accident didn't bear thinking about.

I am always very wary of unmarked military vehicles, apparently of armoured construction, especially if under police escort.
Two rear axles instead of one, or twin wheels instead of singles, are also something of a giveaway.
