Thanks for your input guys! So the axle is correct and rated for 4500lbs, and yet the total weight on my truck is reduced despite GM specifying that it can handle the original total weight with this axle... I wonder if perhaps rather than load itself, it's got something to do with load placement? It is a fire truck after all, I believe it was at some point equipped with a water tank... Perhaps the tank is considered a fixed weight, and the placement of the tank meant the load rating on the front axle would be exceeded if the car was also loaded up with other stuff up to the original max rating? If that's the case, perhaps it is as simple as pointing at the makers plaque and ask them to adjust my papers as the water tank has been removed and the cargo weight can be positioned more freely and thus one should be able to haul more weight without exceeding the front axle rating...
