One of my cousins has spent much of the past 35 years moving permit loads all over the country and Canada. Mostly as an owner/operator for Keen, the past few years driving someone else's rig.
Showed me a picture once of his Pete hooked to some huge thing on a trailer that had a ridiculous number of axles under it. Asked him HTH he ever got that thing moving.
Said getting it to move was fairly easy. Getting it to stop where ya wanted it to stop, took some pre-planning.
