Start a vehicle construction somewhere. Stick solar panels and several car/truck batteries on it. (although solar panels have been nerfed now, lol)
Start a vehicle construction in your safehouse. Frames, controls, batteries, headlights, vehicle welding rigs, RV kitchens and water tanks etc…
Just swap the batteries around from the solar plant now and then and never require welders/soldering irons/cooking fires etc again.
Alternatively just stick an engine and gas tank in it and charge the battery with it.
Personally I’ve never gotten around to making one as by the time I’m building a vehicle I’ve usually got a powered integrated toolset which mitigates the need for welders and soldering irons-- and the RNG seems to hate me with regard to stocked garages.

You are forgetting alternators, without alternators on the engine, the engine will only thrust (power) not electricity (epower).
In fact, combustion engines will normally drain electricity due to the ecu and spark plug etc.
