Randy, the
Burro 14' was produced in Escondido in the late '90s. It had a flat door. The hinges should be readily available.
If you have a earlier 13'
Burro produced in Plymouth MN or Sac City, IA, the doors and hinges are entirely different from the 14' model.
Knowing the actual year of the Burro will help someone give you good advice.
