Can you tell if the mounts are bad by putting in gear, pressing the brake, and accelerating to see if the engine lifts up?

Update: Decided it wasn’t serious so drove the truck pulling our boat across country. 2000 miles. Rattle got less intense driving straight, then intermittent, while still full on while turning left. Then it became less intense on left turns, then intermittent and now appears to have stopped. Bizarre and mysterious

Isn't that when you really have to start worrying, when it gets all quiet? :-)

Suspension? Ball joints? Tie rods? Leafs? hangers? Leaf pack fanning? Body mounts? Particularly the bed mounts...

Just a thought and or suggestion...
