I have it in the 2003 Chev. Can't remember the amps of the alt--ISTR 105 amps, not sure.
PT says 1/3 for running so 220/3 = 73 amps and the 60 will pull 90, so the 40 pulling 60 seems right. But that needs a wire upgrade from the 7-pin's.
I put an on /off switch on the "ignition" wire that goes to a 12v source in the camper, not the truck. I have the 20 amp DC-DC with 7-pin input. It does great with constant 20 amps, and pulls maybe 30 amps which the 7-pin can handle ok, and also the alternator at 1/3.
Can't carry a gen in the TC/truck so this is the "gen" if no solar. Have to idle the truck for an hour to get 20AH. With the 40 you could get 40AH but needs the better wire for input.
