Observation--newer trucks tow fivers a bit nose high

The added truck height is killing me, on a good day I am 5'8" and it is a chore to get into the truck. I thought I had measured the old truck correctly but I must have missed something. The odd thing is that the top of the bed rails were very close to the same height as the new truck but somewhere, the bed height grew. Thanks for the responses.
