I do run lower air in the rear if I'm going to be staying in one place a week or two. RAM has, at least on the 2011 2500, a 45 lb empty and a 70 lb loaded (rear SRW) recommendation in their manual, and IIRC, on the door jamb, and the TPMS is adjustable by pressing a "Light Load" switch on the dash. With the switch active, it will set 45 lbs as the "set" figure; deactivate the switch and it sets the figure to 70 lbs. And yes, it does make a heck of a difference in the ride when we go sightseeing. As for filling them back up? I carry a 120v twin tank aluminum air compressor in the front compartment with coiled air hoses (2x25') that will reach every tire on the truck and trailer. Takes about 10 minutes to air back up and well worth it for the ride improvement on the rough roads we tend to like to explore on.
