Well, Jackie Chan would be proud of such a speed with his "fists".
I was kind of "towing" the airplane parts on Imandra with a small blue crane on a Voron Grad. That "jiggling" happened after the load was somehow stuck on something.
And I do not really mention the obviously "shit type" collision model of that load. The route is shit with respect to clearances, the load is shit with collision model - and even the crane is somewhat underwhelming
To be constructive: Transport dynamite or a harvester to some parts of the route, clear it from trees and use a better collision model for a large trailer with a wide load.
