Last we checked header trailers were ball hitches - would be very useful if they attached like the vanilla in-game pickup trucks do.
Camera issue might be hard to replicate as others have reported different behaviour - basically going from 3rd to 1st-person view in certain cases the 1st person camera view resets to the middle seat like if it were a tractor, instead of offset to the left behind the steering wheel. Might be a mod conflict but details have been mentioned below in this thread addressing the camera issue.
