2008 400hp, I've never used it, for the same reasons you gave.  I am  more concerned with the strain on the engine when lugging it, than saving pennies in fuel costs.  I haven't had the Cummins seminar, but I would enjoy attending someday.

Ordinary personal computers have a power supply that converts 120AC to 12DC, but they are limited to the amount of current that is designed into a PC, and not the current consumed by electric motors or other higher-amp devices.  If you go with your #10AWG idea, be sure and put a fuse or circuit breaker near the battery positive end.  It would be easy, and dangerous, to accidentally drop a hot lead onto something combustible.  I like the other tips suggested.

Mine are OK, as they were inspected at Source Engineering in Coburn, Oregon last year.  Source manager Jim knows Monacos and manufactures improved rear trailing arms for Monacos.
