i used my sides today and i had the ram 2500 loaded down pretty good with maple. i figured id check out the leafs and the helper spring was just about flat i still had some more room too. on the way i figured id stop at the scale just to see how much i had in the bed. the truck normally weighs 5420 with 1/2 a tank of gas and without me in it today it was 7760 with half a tank of gas and without me in it. i couldnt believe it 2340 lbs in the bed abd i still had more room lol. good old ram who says its a 3/4 ton lol.....Mike
