If your trailer has the height, you can look into those mobile home doors with the frame that has screw holes built all around it.
Some of those doors can be modified to be shorter but they're a lot of work to do that. You can sometimes pick those up at used goods outlets.
I got one to use on a chicken hen house not long ago. I think I paid $35 for it and it had a dead bolt installed.
