NHTSA recall 16V564000

What's wrong: The affected vehicles were incorrectly built with a 18,000 lb rated fifth wheel pin box hitch instead of a 21,000 lb rated hitch.

Why it matters: If the vehicle is loaded to a weight greater than 18,000 lbs, the pin box can fail, possibly resulting in the trailer separating from the tow vehicle and increasing the risk of a crash.

The fix: Keystone notified owners, and dealers will remove and replace the pin box inner with one rated for 21,000 lbs, free of charge. The recall began on August 5, 2016.
