I had so many old demolition bricks in the bed of my Chevy truck once that it almost got on its hind legs and walked.
The front tires managed to stay on the ground.
Lol!
Reminds me of the time we packed a washer in the back on my dad’s 74 land cruiser only my dad did tell me that the back air shocks were deflated. We did okay for the first 30 miles until we hit an icy patch on an over pass on the highway. We did a full 360. I did 45 mph in the right lane the rest of the trip into town.
