I read your post and thought what rubbish.
I apologise, I calculated the figures for our 3000kg 109E and with 5 pob @ 130kts cruise @ 3000' you could actually do that at the old weight of 2850kgs, assuming 200kgs per hour at 130kts at 3000' and 85kgs per person, 5 inc pilot. [ And before anyone says it no i didn't go to the flight manual for the fuel flow, just a quick estimate based upon operating it].
You would run out of fuel on landing but you could in theory do it.
With a 3000kg machine you could do it with 75kgs a side as a reserve.
You live and learn.
