It always amazes me when individuals think their RVs are exempt from a basic principle of physics. If the opinion of mechanical engineers holds no sway, I doubt that the warnings from the manufacturer of a gooseneck adapter will, either, but here's what Cody has to say about the use of their
Cody Coupler gooseneck adapter (added emphasis mine):
A word of caution is in order about the use of the Cody Coupler! Because of its design, additional pressure may be placed on the "King Pin" of the trailer it is mounted on. This is a result of the leveraging action involved. Because of this, we feel it is wise to mention several steps that should be taken by the owner of such a rig. These are "common sense" suggestions that could and should apply to any type of trailer hook-up.
REGULARLY INSPECT THE INSTALLATION OF THE COUPLER
Make certain the "King Pin" is securely attached to the Pin Box. Occasionally, additional reinforcement might be advisable.
AVOID THE "POP-A-WHEELY SYNDROME"
Smooth, even starts and stops are always better than the jerky motion.
TRAILER BRAKES SHOULD ALWAYS BE IN GOOD WORKING ORDER!
And properly hooked up.
Caveat emptor....
