Another brand we had looked at before we even had the F150 was Crusader. Their pin weights are in range but wow, their weights don't make sense. For example, the 290RLT has a pin weight of 1200 and a dry weight of 8554, is this even possible. On top of that, the CCC is 3039 (where would you load that much weight?). So do they just throw pin weights out there? how can you figure a pin weight if the manufacturer is not being realistic with their numbers. Can a dealer obtain a real pin weight? (I have a tongue scale for TT's but no way it would work for a pin.
Sure it's possible. 1200/8854 = 14%, which is just below the "normal" range of 15-25% pin weight. For any given design, more or less weight can be put on the pin by moving the axle location backwards or forwards. Think of the trailer as a teeter-totter with unequal arms. If the pivot point (the axles) is exactly at the center of mass, there would be no weight on the pin. Move the pivot point back (away from the pin), and more weight will be placed on the pin.
Since most FW have both a bedroom and a basement in the nose, having a slightly low dry pin weight is probably a good thing. A lot of the weight (WAG: 25-50%) you load into the trailer will be carried by the pin, and so the loaded pin % will increase into the typical 15-25% range.
As to the CCC, I don't think they worry about where it goes. I think it's determined by the design limits/ratings for the frame, axles, and tires.
