vipermanden,
Yes I have. My GVWR is 13,000, GAWR Frt is 5600 & GAWR RR is 9375.
I had my rig weighed at a truck stop Cat Scale. Aux Tank was full (50Gal). Main tank was almost full (approx. 56 gals) cause I had to drive several miles to the scale. Truck and camper were loaded with every thing I normally carry when camping. I keep black and grey tanks empty when towing and fresh water tank at 1/4.

Cat Scale reading were:

Steer Axle: 3200 Lbs
Drive Axle: 7140 Lbs
Camper axles: 12320 Lbs
Gross Weight: 24660 Lbs

margerush,
Can you tell me the part number of your locking gas cap for you 50 gal aux tank and where you got it. I was looking for one when I had my tanks installed but couldn't find one that would fit. TransferFlow couldn't tell me which one would work. Thx
