2003 lance 1171 and 2017 Srw f350 am I asking for trouble?

Seeing semi-trucks on autobahns doing 130 mph, I think the issue is not the weight, but vehicle design.
I drove several luxury DP and lot of them had brakes working "let's push it and see what happen".
It took Prevost with DD3 system (drums not rotors) where I was confident to stop "on a dime" regardless over 16 tons of weight.
I hope never to test it, but I think on my F350 brakes are way stronger than camper ties.
But real issue is how the combo would handle emergency avoiding maneuver.
