The hitch that the dealer is installing sound just fine for your needs.
However, I highly recommend improving your towing experience by investing in an upgrade to the 'pin-box'.
I installed a TrailAir Tri-Glide and "LOVE" it !
No more chucking, the jerk-pulling- back and forth between 5th wheel and truck over miles of roads..... and the airbag absorbs those nasty sudden dips and bumps, the ones that jar your teeth...not to mention saving stress on TV and 5th wheel frame.
