Hey Jim, I would need to know what pin box you have on your 2019 Keystone Montana 3701LK to be able to determine which pin box replacement you need. Can you check the pin box on there currently and see if you can find the tag with the info on it and get me the numbers? Or if you check out the attached help article you can see how to measure your current pin box to determine what you have.
