Impressive weight back there. I'm curious how much the rear was squatting (if any). Did you snap any pics?The 6x6 is overkill for average use. Unless you need the weight carrying capacity. I put a good 6500lbs in the back of a 4x4. The frame has arms that stick down a bit with rubber bumpers, the suspension squats down a bit and the bumpers sit on the rear axle with heavy weight in the bed. I drove around just fine like this. I have a detroit locker in my rear axle. But there really isn’t anywhere to go off roading near me, that I wouldn’t end up stuck between two trees.
There was a post here where a guy put a shit load of small rocks in the back. More than double the advertised payload carrying capacity. He disconnected the CTIS to inflate the tires properly for the given load. I could barly make out if it was squatting in the rear. It looked good.
