There is a "dimple on the hinge" that causes the "friction fit"... You should be able to modify the hinges to eliminate the friction and use your existing hinges...

You likely can't order hinges from an RV store for your door. The door and frame are sold and packaged as a single unit, not individual parts. If you do find hinges, replace them on your existing structure, find you need a new door, you likely will also not be able to order "just the door". I think you'll run into some significant frustration locating hinges, then finding that won't fix the door "coming apart" and will wind up replacing the door, only to find you can't buy the door and will end up replacing the entire unit: door and frame... that unit is available with either "friction hinges" (as you now have) or "non-friction hinges" which is what you're trying to achieve....

Keep in mind that if you do move to "non-friction hinges" you're also going to need a means to keep the door open and "secured in one place". Most trailers have a "door latch" (they come in various styles) to secure the door when open. Some trailers, because of the awning location, can't be opened fully and many of the "door latches" won't work because of obstructions. So, think beyond replacing the hinges to the final outcome and how it will function. If you can devise a means to keep the door secure, no problem, but trust me when I say, "It's hell to have the wind rip a door off the hinge because there's no way to secure it when it's open." ….
