I noticed that your steer axle weight went down by 20 lbs when you have the trailer attached. This would seem to indicate that your pin is slightly aft of the rear axel, and at least 20 of your 80 lbs is from lifting the front end. Since I don't have one, I don't know much about fifth wheel hitches, but my brother has one, and his hitch slides forward for driving, and aft for maneuvering. Could you possibly have yours in the aft position? You might try to move your hitch forward, just an inch or two, and get a little of that weight forward.
