Have you ever driven a car/truck on two wheels?

Three times. Just before I drove them onto the roof.

I popped a wheelie in an older muscle car one time. But I've never just been on two wheels on the same side. And I sure wouldn't try it in an older Jeep.

I've also been on just two wheels while offroading. I think it was front right and back left in a tight spot. I bounced it a little and the front end came off the ground. When it landed I was on the two wheels on opposite corners. A couple seconds later I had cleared the hill.

Yes, it a rut while off-road
