Well, I'm going to agree with Dog Trainer and LarryJM on this one, it's the only thing that makes sense. That was my original questions, how is the manufacture receiver rating affected by this added weight.
Yes, I do have a 1/2 ton truck however The F150 HD is a slightly different animal. 400 lbs. of firewood in the rear and I'd get very little squat. I never asked about the capability or overall payload capacity of my set-up, it's well within all limits, the question was only about the receiver limits and weight behind the rear axle. I'm good with the idea that this weight only affects the weight that needs to be transferred and has no bearing on the receiver limits.
