hi, i have a 90 E350 with a 16ft deck, the regi says its NET 2416kg from factory and the GVW 4900kg, went into ICBC and asked if they could raise the GVW and they said sure no problem to 14,000lb, but my door post still has 11,000lb max on it how can that be? who would be right ICBC or the door in case of accident? I was told by the agent re weigh truck on scales as I know the NET is way low as thats what it weighed cab/chassis not with the deck etc on. they then said the take the NET and multiply by 1.5 for the GVW, I also know of a guy who has a F450 tow truck and the door post has 15,000lb on it but ICBC has it at 18,000lb, just want to know what the legality is and why or why not bump the GVW and what it means to the door post rating etc thanks, also does it change as it was a cutaway chassis from factory? and never had a completed net and gvw applied to it (just trying to read the legalities of the MV act text)
