so I am really surprised to find that I didnt add any weight it seems. The truck is lighter than with all the IFS metal and the added wheel/tire combo is heavier but it all turned out to be a wash. I pulled up to the scrap yard and it tipped the scales at 5150lbs and see the after pic below. before it weighed 4700lbs and it will again when the front driveshaft and axle shafts go back in.
