Just remember to leave a margin for error. Adequate clearance on a nice level parking lot is not necessarily going remain that way when trying to back and turn up or down an incline since that will will further reduce cleareances between cab and trailer and/or bedrail and trailer.

Also watch the pin placement. You really don't ever want the pin to be anywhere behind the axle particularly if you are at or near capacity as this will translate into poor handling characteristics and lifting of the front end.
