Stripping down the Trailer

Before I can rebuild the Trailer, I have to strip it down. It just makes logical sense. In doing so, I have made two observations.
One: It's not in all that bad of shape. It may look less than pleasing, stuff is loose, the lights didn't work, and the winch was frozen, but the basic bones of the trailer are in very good shape. Once all the rust is removed and the metal repainted, it will look good as new.
Two: I am not dealing with "standard" non metric hardware. All of my cars and my Land Rover have been from Europe, I have a very large collection of metric tools, I am not about to buy standard tools to carry along also just to do either maintenance or emergency repairs. My tool bag is almost too heavy to lug around as it is, I do not want to add to it. Thankfully all bolts are thru bolts with nuts, so this is not too bad a job. I may even go Stainless. (yes, I know it galls)
