Good morning fellow RVers!! Have a question. We just had a new B&W Companion 20k hitch installed in our 2014 Ford. It's the hitch that fits the factory installed holes in the truck bed. This new hitch plate appears to only move or rock forward and backward. It has no side to side motion, which is unlike our previous hitch which had motion in all direction. Is this normal?? It seems to me that there should be some side to side motion as well as roads are not always level. The previous hitch was a 16k B&W.
