Bits like tow hitches are the sort of stuff 1:16 is good for - you can but them off the shelf. Making them is a pain in the rear as you solder them up and then try and solder them to the hull without them falling apart. Different solder temperatures help but they are not so easy to buy anymore.
You can actually se the problem caused by the gearbox in this picture...the hull is not flush with the glacis at all. That really toasted my flakes.
