CR weighs the haulers and puts on a sticker that states the final dry weight and the initials of the person that weighed it. Dealer left it on my 3612 and it was 11,718. Kept it with all the manuals and documentation. I believe the weight you listed is the base model, which included one AC unit. Mine had all other options except auto level.
I pulled it with a Dodge 2500 quad cab long bed 4X4 diesel with 3.73 gears, 4 speed auto and had no issues, plenty of power. It was a 2005 truck, but went to dually in 2014 to travel more and upgrade to a bigger hauler. I really like the 4.10 gears I have now, with the six speed auto.
