Thanks Javi. My previous truck was a dually too but the 405TS was above it's max capacities...
I stopped at the weigh station right after getting the camper (with the old truck). Had some difficulty communicating with the attendant so my weight with the 2 disconnected had my entire truck on the drive axle scale instead of separated but it confirmed what I already knew...
Disconnected
Truck: 8640
Trailer: 17,200
Gross: 25,840
Connected:
Steer Axle: 4,820
Drive Axle: 8,300
Trailer: 12,720
Gross: 25,840
6.0 specs (from the door sticker):
Front GAWR: 6,000
Rear GAWR: 9,000
GVWR: 13,000
The GCWR is not listed but from what I can find, it looks like with my axle (4N, 4.10) it's rated for 23,500.
Sooooo.... I was 120 lbs over on my GVWR and 2,340 over on my GCWR.
I'll try to re-weigh this coming week with the new truck but I'm certain I'm under all the ratings now.
