Dunecrawler do you have the skid plates on yours? That might have protected the steering boots.
Not really sure about airing down the tires not helping much. I have not driven a truck that it does help greatly to air down. I have taken mine on the beach and haven't been able to get it stuck. Then again we are not transversing dunes either.
No skid plates there, but to be honest, the boot thing was our own stupidity. I should have known better.
