The simple truth is that the optimal tire pressure is a function of the weight that tire is carrying, and there is no magical one-size-fits-all pressure. If you put in enough air to safely carry a heavy load, then run light, you will get a hard and squirrelly ride, as you experienced. If you fill to optimal for a light load, then pile on lots of weight, you’ll get a wallowing and squirrelly ride. It’s directionally unstable both ways, just for different reasons.
Although you can’t weigh every time you start the engine, you can adjust the pressure to light or heavy pressures based on an estimate.
Running a big class a motorhome with under inflated tires, will get you some instability alright and especially with the $ damage of a fender well that gets blown out, along with the tire. This at best and if a steer tire, keeping it in your lane, might be a challenge for some.
