Have any of you ever heard of Lock N Roll hitches? I spoke with an avid off-roader who had one on his teardrop trailer and he swore by them! He is able to negotiate very rough terrain while pulling his trailer. The hitch alleviates stress on the tongue and frame by allowing the trailer to move up and down on the hitch as well as side to side. Your trailer cannot come off the hitch because it does not use a standard type ball. This hitch may be the answer to many of the problems FGRVers have with their trailer frames. Here's what the manufacturer says about their product:
This is a heavy duty product. These hitch and couplers are designed and manufactured by a blacksmithing family who trace their skills back five generations. All units conform to the requirements of SAE standard J684 and are tested by independent labs.
360° ROTATION & THREE AXIS OF MOVEMENT
This eliminates twisting damage to vehicle & trailer frames caused by sudden changes in vehicle-trailer orientation while on a construction site, farm, or off roading.
POSITIVELY SECURED CONNECTION
Once the latch plates are locked in place Lock N' Roll® will never pop off like ball hitches do. Everything is in plain view to eliminate any question of whether or not the trailer is hitched correctly. The positively secured connection keeps you in control so minor mishaps on the road don't turn into major accidents.
EASY TO USE Lock N' Rolls® wider range of movement makes it easy to couple and uncouple.
Lock N' Roll® provides a very tight, close fitting connection that eliminates "thunk & jerk" action of conventional hitches. Nearly any terrain can be negotiated safely making this hitch ideal for off road (4x4), as well as horse trailers, boats and RVs. The 360 degrees rotation along with the left to right and up and down articulation allows fantastic maneuverability especially when backing a trailer into position.
