Not specified means there is no law regulating the act of doing that.
In fact in this state (AZ) it is legal to ride in the back of a pick up truck (the bed) in anyway you want*, however if you ride in the cab you must wear a seat belt.
* As long as the load (In this case people) are secured. If the load/people fall out of the bed the driver has some problems. Otherwise the driver is good to go. Street, highway, or freeway, and I have seen it almost every day.
On the shock vertical versus horizontal - it is all about the valving as to whether the shock can be horizontal mounted.
