Hi Lilly, I have a '12 GMC 3500HD dually 4x4 and it is high from factory. I'm 6'1" and I have to stand on a stepstooljust to get up in the thing. I just picked up my Redwood with the Trail-Air optionand just as I suspected, the RL rides nose high. I can drop my Reese Elite another inch, and possibly raise the Trail-Air one notch, but I don't think that will be enough. Maybesomeone will post who has the standard pinbox and let you know.
