It will therefore draw over 40amps from the main system to run it. The hilux has an 80amp alternator so you have now consumed over half its continuous rated output.
here is a scenario
So you have been away camping for the weekend, aux battery is down and its time to go home. Its 8pm and still 35 degrees in the middle of january
45 amps redarc
15 amps spot lights/lightbar
10 amps head lights
5 amps park lights
10 amp ac and fan(providing its on a low setting more if you like your fan fast)
so if you add that up we are now at 85 amps and i haven't factored in current consumption to run the engine electronics, radio and other minor components.
my suggestion is don't use the 40, use the 25 or 20
