"I'm within my weights, therefore I'm safe" is not a valid conclusion to make.
I lived 11 years in Germany, so am very familiar with the autobahn. Considering it's actually hard to get a german license, extensive classes, 30+ hours of professional training, high cost....(formula one course essentially)
The speed limit is what you can SAFELY travel for your given VEHICLE, LOAD and road CONDITIONS. Yes, they can give you a ticket for excessive speed with a swaying load, even if there isn't a speed limit for that stretch. (most tickets are a precentage of income, thus they all hurt the same, rich or poor. One rich driver had a $120k speeding ticket.)
Most trucks and trailers are limited to about 60mph, the MFG can actually put a speed limit sticker on the back. (just like UHAUL trailers) and the cops will use that as your limit.
