If you simple look at the maximum weight we can carry on GK, and convert that to pounds... I see my max weight (2250 kg) is about 4900 lbs.. .thats more then 2 tons...
Now lets just ask ourselves, do we know anyone that can literally carry 2 tons??
For you that dont know 1 kg is about 2.2 LBS
And those that are too lazy to do math use this..
