I had this made locally, and couldn’t be happier with it. It’s made out of heavy duty black vinyl to match the Jeep top. It secures to the trailer using a long length of bungee that runs the perimeter of the tarp, inside a tube sewn inside the outer edge. The tube has cutouts that let the bungee out of grab the tarp hooks on the trailer.
Some PVC tubing makes inexpensive and handy tarp support bows.
This trailer mod comes courtesy of the Bantam Trailer List, with a great blueprint posted in the Files section (membership required).
The supports are 1/2” schedule 40 PVC pipe with some 90 and 45 degree elbows. I didn’t even glue things together - keeping the unglued lets me shift a bow assembly back and forth by pushing one side at a time.
Here’s another way to get organized while camping—use some of the plastic drawer units available from places like Wal-Mart to store dry food in.
While driving, these get pushed to the front of the trailer, and the tent/chuckbox gets packed in the rear. The only challenge with this arrangement is if you need to get into the drawers before setting up camp or after breaking camp.
Note that I had to buy both of these in the 3-drawer versions and remove one drawer. Cost was about $35.
New bike rack design puts the bikes up top for more hauling capacity in the trailer.

One option for the civilian Bantams was the covered wagon (or chuckwagon) style canvas shown in the picture from the sales literature of the era.
