Got a 2500 duramax and go to the beach and even tow trailers on the beach sometimes too. Pismo beach gets very washed up during high tide with super loose sand and sometimes having to go up little slopes to avoid being washed by the tide. Have you had experience of graps on a heavier truck. I think they would dig too much.
The reason people get stuck in the sand is they have no throttle control. Mud tires generate more traction but driver needs a little feel for what the tires are doing.
