Used to tow the Sea Land containers on their trailers in my convoys in Vietnam, from the port city of Qui Nhon to the central highlands city Pleiku. I thought it would be fun to have one on a piggyback to tow on my garden layout. I found a trailer frame on eBay, made the rest. I used metal foil duct tape for the metal 'look'. I made the lettering on Paplio ink jet vinyl, just cut it out, peel and apply.
