I don't believe all doubles are unsafe, in fact I'm not sure any doubles are unsafe.

I don't see how a properly hitched double (like THUNDERUSONE's) is less safe than what Minnesota requires. A fifth wheel (and a king pin) could come loose just as much as a ball/hitch.

as i said unsafe depends largely on LACK of proper equipment/preparation & skill, too many rule them out on SIGHT alone (based on their own skill or opinion).
