Inverter advice?

[Teligence]

Looking for inverter options.
1. I have the 136 amp alternator, so how many amps does the truck require to idle with no other accessories running? I need this so I can determine the max sustainable power output to determine an appropriate inverter size.
2. Along with this, I'm looking for an extra battery kit that I can connect the inverter to, that will automatically charge when the engine is running, but won't drain the engine starting battery.

You will be looking at a dc to dc charger or a relay kit to connect the 2 batteries. What are you looking at running off an inverter? Honda quiet generators or generac whisper generators may be a better option than a big inverter. There are even dc inverter packs. Milwaukee has one that I’ve used for work a few times running power equipment. It has an 1800 watt sustained running load and a 3600 watt startup load. A bit on the expensive side but you can buy extra batteries and rotate them through and it has a built in charger. Supposedly the next gen version will have a solar capability albeit I doubt very useful at all. Most smaller solar systems are bogus at best.
