I think your problem can be solved without buying new hinges by using some elbow grease and analytical thinking. It does not look to me as if your hinges are fractured. If you are handy with tools you can DIY this job. If you are not handy or skilled or don't have the tools then take the hinges to a local person who does things like metal work and welding and let them sort out the problems for you. There are a lot of blacksmith types and garage mechanics around who will do odd jobs for a six pack or two of beer and a little cash. Or out in farm country there will likely be an agricultural blacksmith around who earns his living doing repairs to metal objects.
DIY instructions:
I can see just by looking at the photo that you need to replace the hinge pin as it is bent in the center. First step remove the hinges from the door and the frame and then remove the hinge pin. You might need to drill out or grind off at the top and possibly the bottom of the old pin to be able to slip the hinge off the pin. That task is best done with the hinge held steady in a bench vise or at the very least clamped securely to a board that is also held steady. Do not try to hold the hinge in your hands while working on it. After you get the pin out measure the diameter of the old pin with calipers and go to the hardware store to find something suitable for a replacement. If you don't have calipers your neighborhood hardware store will have a pair around. If you can't find a pin of a suitable diameter one can be quickly fabricated on a metal lathe using some steel rod.
You might need to cut the new hinge pin to a shorter length using a hacksaw or Dremel tool with a fiber cut off disc, smooth the cut end. While the new pin could stay in place by gravity alone you may want to peen over the bottom end to keep it captured. Or if you have a drill and tap set you could add a set screw into the knuckle of the hinge that will act as a keeper to retain the pin. You need a pointed end or rubber tipped set screw for that task of securing the pin. The set screw should only be reached from the inside of the door. You don't want someone getting into your trailer by pulling up the hinge pin which is why you need to go to this kind of measure of securing the pin in place.
If the hinge has been deformed from the
weight of being out of alignment you might also need to do some straightening of the hinges with an anvil and ball peen hammer or vise and hammer. Do check the frame areas into which the hinge is set to make sure that framing is not bent and that the holes the screws go into have not been oversized. Epoxy putty sticks, the kind you knead to mix are the best for filling oversized screw holes. Don't
fall for the stick in a tooth pick fix, That is a poorly done fix for longevity of purpose and should only be done as a temporary emergency solution.
As to the task of finding a suitable replacement hinge if those original hinges turn out to be badly fractured ...which would be about the only non recoverable situation.... In these situations it is all about keywords...in this case "heavy duty offset door hinge". Then use those keywords in an image search. It is much easier to quickly sort through hinges by looking at photos of them. To check if the hinge you see is going to work then you will need to know the measurements of the offset of your original hinge and compare that to the new hinge. There should be a measured drawing on the seller's website showing those dimension that you will need to take on your original hinge. Without knowing those dimensions taken from your hinge I could not even begin to tell you what hinge I might see on the internet would actually work as a replacement hinge for you.
