Torque, if you think it will get rather cold and you are parking the beast outdoors, I'd be sure you've added some good fuel conditioner to lower your cloud point.
Other than that, my only other suggestion is when you fire it up the first time after sitting awhile, pull fuse #9 from you box and crank it over at least 10-15 seconds to get some oil circulated before you fire up. Cummins recommends this. The longer a rig sits the more oil drains out of the oiling system back into the pan and it takes a little longer to get oil circulation once you do finally start it again.
