OR, if it's pouring rain, you could always slow down a bit...that's saved my fish-tailing boat many a time. I have a strict "65 or less" speed limit when I'm dragging the love of my life behind me, 55 or less in heavy rain. And that's with just one boat.
But 6 of them stacked? I think 55 might be the max on a dry road, less in rain. And then there is the cross wind issue too, on a stack like that, was it blowing hard when this happened and from what direction?
I heard one of the drivers (on the way out to IA) say that the mega-trailer's top speed was 60 mph. Started getting squirrelly above that.
The wind was from the rear quarter - SW as I recall. On my rig, I remember going from 11 mpg to about 15 as soon as I "turned the corner" and headed east at Iowa City on I-80.
