Nice! I have a 47 or 48 T3-C that is mostly stock except for the hitch (I use a Max Coupler). I am the second owner of my trailer, it was in the same family until about 10 years ago. I was going to build a lid for mine but I mostly use the trailer to carry a Hobie Pro Angler kayak so a lid would not work too well for this.
Are you using the stock suspension?
What are you going to use for a hitch?
If your Bantam came with the military wheels they are worth selling to the early military Jeep crowd, they can bring serious money if in good shape.
