Trailer shake

Thanks for all of the suggestions. I always put blocks under the stab jacks since we usually camp at Myrtle Beach, which is where we are now in the first extended trip in the new trailer. .And yes, I have to recheck them often in the sand down here

I think I will find some x-chocks while here and use them as a start to see how things work. Then once home, add scissors jacks in the center if needed.
