Having been around a M1000 for a while and operating it with and without a load, I think something important to point out is that the 3 trucks mentioned in the M1000 TM as being appropriate for the M1000 (M1070, M911, & MK48/16) all have not only 3.5" kingpin fifth wheels, but somewhat similar ways of mounting that fifth wheel to account for the additional stress of steering the trailer.
I'm unsure of the M911 or MK48's air compressor, but the M1070 has a 4 cylinder, 30+ CFM air compressor, presumably to handle the demand of the CTIS on the tractor, but also a trailer with 10 brake chambers.
