Motorhome sway
My 40 Foot Class A after a long sweeping right turn and an immediate left turn at 20 mph almost rolled over. I've made many left turns at a greater speed without that reaction.

Being a newbie but as a former Bike Cop and sailor, I pictured your rig healing (leaning) to the left during the right turn. If you turned quickly to the left, the rig was already leaning that way and would tend to show you just how top heavy it really was. Just an inexperienced but educated guess.
