Just wondering how much the stock rear sacs in the 20ssv hold in water weight,and does anyone know the dimensions of the sacs?

I believe they are 16" X 16" X 30" each <BR> <BR>Formula: <BR>L' X W' X H' = Cubic Feet <BR>2.5 x 1.33333 x 1.33333 = 4.44444444444 Cubic Feet <BR>4.44444444444 Cubic ft x 7.47 = 33.199999999999996 (GAL) <BR>33.199999999999996 Gallons (US) = 277.0627684 Pounds <BR> <BR>Hope this helps. <BR>

Thanks Chris.
