Hello Garrett, thanks for reaching out. We do carry a few different ramp door hinges, but there is no way to look up your trailer to know exactly what hinge you will need. RV manufacturers just are not that specific with their online literature. The best way to determine what you need will be to compare the dimensions of our hinges to what you have now.
For example, the Ramp Door Hinge # PLR1902. This is 8-3/16" long overall, and it has a 1" pin diameter. I have included a picture with more detailed dimensions.
If this does not match what you have, just let me know the dimensions of the current hinge and I am happy to look into it. There is no way to add pictures on here, but if you want to email those to me at [email protected] I can definitely take a look.
