It's not as much as twist as it is how large of humps you go over. Twist is part of it but damage is probably most likely to occur when going over a big hump. But like you said bed clearance is what matters and you can't answer your questions without seeing the actual truck/trailer configuration and associated clearance.
As high as new trucks are nowadays, we're seeing less clearance, sometimes down to 6" or less.
With a travel trailer, articulation is virtually unlimited for all practical purposes. Everything will twist until the hitch binds on the hitch ball, which would be a situation we should never be attempting to tow a trailer through in the first place.
