I have used a Dodge 1 ton 4x4's DC alternator to charge LiFePO4 batteries. Batteries connected to 1500w inverter. Charge rate was over 60 amps and I could probably have gotten more if I messed with the alternator controls. But that was more than sufficient.

The vehicle was somehow modified to accept a Power Take Off and part of the mod was to change something in the power train to allow the vehicle to idle for long periods of time without damage to the transmission system. Something about lubrication. I never got a clear explanation of the system.

So now I have a Toyota Tacoma. Same batteries and inverter, but a much different vehicle. Especially the electronics. Anybody messed with using a Tacoma in this configuration?

In general DC to battery to inverter works well. The gotcha is how the vehicle reacts to long term idle. When I was doing Red Cross stuff, I idled one of their ECRV's (electronics truck) for weeks at a time. Never could find out if the vehicles were stock or modified.
