Here is info from the 6066 GMC Jolly website for GMC's; Jolly get's all the credit....remember GMC V-6's are a bit heavier....Thanks Jolly
With that said, I'll give you the info on 64-66 GMC Trucks, as I don't
have the Chevy info. This comes from the 1966 Dealer Data book.

That is for the base chassis & cab with V6 three speed no options. The
bed was an option so you need to add bed weight for pickups. Bed weights
come from the 1962 Dealer Data book.
6-1/2' wide side 395
8' wide side 470
6-1/2' fender side 360
8' fender side 420
Panel Truck 650
9' fender side 825
10-1/2' Panel 800
The Panel Truck is an option for the Pickup, not the Suburban.
In the 64-66 run you could get a inline Chevy engine as well, they show
it's not rated as high in GVW for the 1/2 ton model. Here are the GVW &
GCW ratings. GCW is your towing weight
1000 - GVW 5200, GCW 8000
I1000 - GVW 5000, GCW 8000
K1000 - GVW 5600, GCW 8000
1500 - GVW 7500, GCW 11000, I & K series too
2500 - GVW 8800, GCW 14500 single wheel
2500 - GVW 10000, GCW 14500 Dual Wheel
So by these numbers you can see that the inline six 1/2 was rated less
than the V6 model only on total truck weight, towing is the same. 1500 &
2500 series all share the same numbers for both GVW & GCW.
So if you have a V6 powered short wide bed at 3735 lbs, that leaves you
1465 lbs for passengers & load, which is about 3/4 of a ton, so with two
good sided guys up front, your total load you could add would be about a
1/2 ton or 1000 lbs.
