Can anyone clear this up for me? What were the gross weights fully fueled, crewed and loaded for these vehicles?

Here's a direct quote from "Canada's Fighting Vehicles", Canadian Military Historical Society:

The curb weight of a vehicle as given is the weight of the complete vehicle (front or rear axle as stated) less all personnel, but with full tanks of gas, oil and water. It includes tools normally with the vehicle and built-in equipment as delivered from manufacturers.

Laden weight is also termed "maximum gross rating" and "gross vehicle weight". It is defined as grand total weight of complete vehicle, fully equipped and serviced for operation, including maximum payload, and personnel with full kit.
Payload is calculated by subtracting curb weight from laden weight. For calculations, the weight of a man with full kit, including kit bag, blanket, rifle and ammunition is taken as 240 pounds.

Hope this helps.
