If considering towing a trailer behind a Keystone fifth wheel (the owner's manual prohibits trailer towing with conventional travel trailers built by Keystone) take a few minutes to go beyond the sentence in the Owner's Manual that says the receiver with safety hooks and an electrical connection "ARE RATED 300/3000 pounds".....
Just beyond that are a series of statements that explain the braking function requirements for any trailer towed behind a Keystone fifth wheel trailer with "OEM receiver". It's not always as "simple as reading one sentence".....
Check out the "receivers installed on Keystone trailers" commentary in the Owner's Manual, starting on page 30.
