Please explain your issue a little clearer.
Is the issues height of bed rail from the ground or the height of the bed rail from the floor of the bed?
If you installed your existing hitch in a new TV with the same bed floor to rail height as your old TV you be fine other than towing nose high (To be discussed later). If the bed rail to ground height has changed, then you could be a little close at the tail gate.
Which is it?
It would good to know what hitch you have, and how much adjustment youhave there and if your pin box as high or as low as it can go.
If you could post a picture of the current situation would be great.
