Can Sidewinder Pin Box Install in Higher Mounting Holes of Trailer with Lippert 1621 Pin Box  

So the installation instructions for the Reese 68220 sidewinder pin box only show one mounting position for the Lippert 1621 style bracket. I did as instructed, but now concerned the pin box sits too low and the front of the trailer will have to be elevated to match up with the hitch and cause the back of the trailer to pitch downward. It is currently mounted per the instructions on the bottom 2 mounting holes. There are 2 sets of 4 holes that I could easily move the box up one or two positions, therefore raising the king pin. I cannot see where it would be an issue, there would still be ample clearance b/w the truck bed and bottom of the camper.... but i cannot find any reference where this is suitable. There would not be a clearance issue, it would actually be a sturdier mounting position, no interference in the rotation.... what am I missing. Thanks
