Question:
Do anyone make custom length hitch rails ? Universal rails are about 43inch do they make rails around 34-36 long Or can you trim the universal rails

They do not make 5th wheel base rails that are 34"-36" long. If they did make a set in this length then they would not be long enough to reach the frame brackets. Instead, they offer two different lengths of base rails which are 43" long and 48" long. They cannot be trimmed. The 43" long rails are known as inboard rails which attach to frame brackets that have mounting holes positioned inside the frame rail. The 48" long rails are known as outboard rails which attach to frame brackets that have mounting holes positioned outside the frame rail.
For your 2018 Ford F-150, you would want to use part # RP50087-58 for the inboard rails or part # RP56034-53 for the outboard rails. If you would also like a 5th wheel hitch recommendation to go with the above base rails then I would need to know what size bed you have.
