Getting stuck in sand

Lower tire pressure, a shovel, boards and a tow rope. Always in the Tahoe.

Air tires down......just be aware you can pop bead and tire off wheel when doing so.

Carpet strips laid down in front/back of drive tires

Slowly apply 'parking brake to load rear differential and control tire spin

Carry a 'sand wedge & winch/come-along' to pull yourself out

Stay out of sand!

I watch a lot of YouTube videos of big RV's stuck in sand on beaches, I am not sure I would want to take a 20,000lb anything on the beach but that's me..

Not sure what you were driving or pulling or....??? but the quick obvious answer for 'stuck in the sand' is to air down your tires ...
