The Reese Sidewinder 5th Airborne Premium 5th Wheel Air Ride King Pin w/ Sidewinder and Turret # ST400-5AS16K that you referenced is designed to replace the Leland 7910, 7920, and 7921 and the Dexter 221-0037 pin boxes. Unfortunately I don't have a way of verifying what model pin box your 2001 Hitchhiker is equipped with, as trailer manufactures don't do a great job of making information like this available and there would have been a few different sub-models of the Hitchhiker that likely came with different pin boxes.
The only way to ensure a proper fit is by identifying the pin box on your trailer. If you can't find any markings on the pin box itself, your other option is to determine its style/size (see attached image) and then take a few measurements of the bolt pattern.
I have included a great article below that explains what measurements you need to take along with a chart that will help you identify the model based on those dimensions. You can also send me the measurements you find and I will be happy to verify its model and recommend the correct Sidewinder replacement.
