If the GVWR is 6,500 lbs and the curb weight is 4,880 lbs, logic would dictate the payload should be 1,620 lbs instead of the 1,270 factory rating. Am I missing something in the equation, or it's not unusual to have these types of discrepancies with the specs?
This web page gives a single payload value of 1270# for all 2014 GC Limited 4x4 versions even though there are three different curb weights depending on engine choice.
It appears that the 1270# payload is for the diesel engine version which has a curb weight of 5275#.
The V6 version has a curb weight of 4875# which is very close to the 4880# you measured.
I think it is safe to say that the payload for your GC is about 6500-4880 = 1620#.
However, you should look on the TIRE AND LOADING INFORMATION sticker on the driver's door edge or pillar to see what is listed for the maximum allowable weight of occupants and cargo.
If you look closely, the WDH shifted 80 lbs to the front axle. Do you think that's adequate, or should I adjust the WHD to add more weight to the front or get rid of the 80 lbs. As it is right now, both the TV and TT are fairly leveled.
I recommend that the front axle load with TT attached and WD applied should not be greater than when unhitched.
It is not necessary to adjust the WDH to make the TV "level".
Does your GC have the automatic-leveling suspension. If so, was the auto leveling active when you were adjusting the WDH?
To properly interpret your two sets of scale measurements, you need to add about 100# to the rear axle load for the second set to account for the missing 2/3 tank of gasoline. You can assume all of this weight should be added to the rear axle.
The indicated TT weight would be (2620+3160+4060)-4880 = 4960#.
To achieve a front axle load increase of 80# and a rear axle load increase of 3160-2340 = 820# would require a tongue weight of about 1200# with about 300# being transferred to the TT's axles via the WDH.
So, either there is a problem with your scale measurements, or you have a very heavy tongue weight for a 4960# trailer -- 1200/4960 = 24%.
