The complete turret weighs 2900lb which is 1.315 Tonnes. I was a bit out on the gun, it's only 110Kg. When we first got the Fox someone told me that the suspension was updated, and if this mod was carried out the code was changed from 7000 to 8000. Our vehicle shows this happening on 8/5/84. Not sure how true any of that is, and I haven't seen any documentation to support it.
