Here are the CAT weights with trailer:
steer axle---4480
drive axle--6500
trailer axle--11020
Gross weight--22100
without the trailer:
steer axle--4480
drive axle--3480
gross weight--7960
Trailer gross weight--14040
Pin weight--3020
truck rating on sticker
steer axle--4800
drive axle--6800
gross weigh--11000
tire rating-- 3620 each
gross pulling weight of 5th wheel--16,300
