A heavy wooden beam such as 2x12 lumber, 6-8 feet long, can be laid across the pickup bed and secured with sandbags, then topped with a high-hat mount to hold a Steadicam rig clear of the rear bumper.
Plywood placed under the mounting point prevents the rig from shifting during shooting.
A short offset arm extending from the high-hat keeps the camera rig away from the vehicle body.
Operator safety requires wearing a harness or belt to prevent being thrown from the vehicle during sudden acceleration or braking.
Selecting an experienced driver minimizes dangerous maneuvers that could destabilize the rig or throw the operator.
A van with the wooden beam run out the back door and wedged under the middle rows of seats using apple boxes, then secured with ratchet straps, provides a stable platform.
Metal lighting stand extensions can be used as a temporary mockup: a horizontal piece clamped to the chassis and a vertical piece mounted to the tow-bar with hose clamps, providing body support during acceleration and braking.
Temporary rigs using lightweight clamps should be backed up with steel safety cables as a failsafe in case the clamps fail under stress.
For permanent vehicle rigs, 2-inch scaffolding pipe with Cheesborough clamps provides safer load-bearing capacity than lighter clamps like Mafer clamps.

The wooden beam method is tested and practical but requires good weight distribution and sandbag availability on set.
Temporary mockup rigs using lighting stands and hose clamps are proof-of-concept only and should not be used for extended work without professional reinforcement.
Lightweight clamps are unsuitable for the dynamic stresses of vehicle-mounted camera work and can fail unpredictably.
No final consensus on best practices for improvised rigs in remote locations emerged from the discussion.
