Why best to go out and actually weigh your setup axle by axle, fully loaded ready to go. If you don't have one (trailer or TV) then use their collective GVWR's as the max possible
If the TV has a GVWR of 6800# and the TT has a GVWR of 8600# and both are loaded to their GVWR's, the GCW will NOT be equal to their collective GVWRs.
The GCW will be equal to the sum of the GVWRs minus the vertical load on the TV's receiver (tongue weight minus load transferred to TT axles).
Your suggestion would have the OP looking at a GCW of 6800+8600 = 15,400#.
However, assuming the vertical load carried on the TV was 80% of 13% of 8600#, (0.8*0.13*8600 = 894#),
your scenario of "max TV GVW and max TT GVW" would give a GCW of only 14,500#.
Furthermore, since the OP has reason to believe the weight of the TT can be limited to 7000#, he doesn't need to assume the weight will be 8600#.
If you load up your TV to it's 6,800 GVWR (including the trailer PIN/Tongue) 6.8K + 7K = 13.8K and on 'paper' it looks like under the GCWR, but betcha the rear GAWR will become an issue
You should do some calculations before you bet your money. With a properly-adjusted WDH, TV GVWR usually is exceeded before rear GAWR.
The indicated curb weight for the candidate truck is 6800-1441 = 5359#.
The empty axle load distribition will be approximately 75% on front and 43% on rear.
This means front empty load will be about 3055# and rear about 2304#.
If OP can manage to keep cab load to 500# (assume 50/50 distribution) and bed load to 100# (100% on rear axle),
the unhitched axle loads will be front = 3305# and rear = 2654#.
Remaining TV GVW capacity is 1441-600 = 841# for tongue weight loading.
Assume WDH is adjusted so 100% of trailer-imposed vertical load is on rear axle.
Hitched axle loads then will be front = 3305# and rear = 2654+841 = 3495#.
For this scenario, the TV will be at its GVWR, but the rear axle still will have 3950-3495 = 455# of remaining capacity.
Rear axle is 3950 rear and 3650 front. 7600 total on the 5.3The rear GAWR of 3,950 will in my guess, the limiting factor for your whole setup
If you consider GVWR to be a factor, my guess is that GVWR will be the limiting factor.
