Some curious and ingenious GMC'er will likely replace the two rearmost drums with in-wheel electric motors and load up some lithium batteries under the bed, sofas, or replace the Onan. These motors could boost motive force (double?) significantly and offer braking. The batteries could be tapped for house electricity with a vast reserve when charged. Charging from shore power, generator (may need to update to a 220v generator or motor attached generator?), or regen from braking are all possibilities.

The mid wheel brakes could remain as well as the standard drivetrain. This would be so cool, but likely a $50k hobby project. Take a look at this in-wheel electric motor write up. These may be used in the new Lordstown Motors trucks that are being readied for market from the old GM plant.

Any thoughts?

Would GMC then count as a 6x4 then? If done right, this mod would be a great addition to the GMCs in the Northwest, where you simply can't go anywhere without climbing a long hill, usually in both directions... The in-wheel motors would "boost" the uphill portion of the drive to take some load off the engine and transmission. Then the batteries can get recharged on the flat road or on downhills.

In Texas I always fantasized about hooking in two A/C compressors on those wheels so you could get nice blast of cold air from your breaking power. This seems much more practical than that at least.
