I have pulled 14-15k with the truck and I've had 8k on the steel flat bed and I would not recommend anyone doing that with similar setup as mine, much less on a 305 1/2 ton truck. Even with my big brakes, brakes are still the weak point.

Arubariba, 1500 applies to 67 and up half ton trucks, prior to that 1960-66 3/4 ton GMC trucks were 1500 series, 1/2 tons were 1000 series and 1 tons were 2500 series
