Assumptions:
Coach weight: 50000 lb
Wheelbase: 300"
Front overhang: 80"
Rear overhang: 100"
Tag to Drive axle spacing: 55"
Tag/Drive split: 35%/65%

Center of gravity location without tongue weight: 219" behind steer axle.
Steer: 15715 lb
Drive: 22285 lb
Tag: 12000 lb


Center of gravity with 1000lb tongue weight added: 225" behind steer axle.
Steer: 15056 lb
Drive: 23364 lb
Tag: 12580 lb

Delta off steer axle: 658.7 lb
