Not being able to drive or ride in the truck makes it tougher to offer suggestions. The noise seems to be happening most often when the truck is not accelerating. It also seems to match either engine or driveline speed. And it sounds like you have a manual transmission. I would do additional testing.

1) Can you tell if the sound is coming from the front or rear of the vehicle?
2) How responsive is the steering when this is happening? Can you feel anything in the wheel?
3) If you can do it safely, try pressing clutch / shifting to neutral and shutting the engine off when the noise is happening to eliminate the engine as a source of vibration.
4) Are there any big left hand turns that you can take to see if the noise happens in both directions?
5) Do you have any links to the truck build? It may not help with the diagnosis but a 4BT Task Force truck is cool.
