I've never weighed the contents of the box, suffice it to say it is full. I share your concern about the hinges and avoid opening the swing arm as much as possible with the extra 10 gallons of fuel on top, in addition I added the delron slides/supports shown in the picture below. The block does a great job of supporting the weight in the closed position and the slide makes closing the loaded assembly a lot easier.
Regarding feeling the additional weight, this is what caused me to upgrade to adjustable Fox shocks in the rear. Now anytime I carry extra weight in the back (fuel, minibike, heavily loaded trailer) I dial up the shocks to compensate. Great modification!
