Then you must have a crew cab long bed truck with that as a maximum weight load. I looked at your dual wheel name and assumed you had a dually. I know that 2011 and newer went up a few hundred lbs. I kind of like the locking differential on the newer truck but mine is paid for. Not worth starting that game all over again.

 

Had a dually crew cab long bed when I joined but now have a '08 SRW crew cab long bed.
