First off, pretty new at this and I have never actually built a car/mobile base before.
I found a fully functional solar powered car: all extra light frame, 4 solar panels, 2 large storage bats, and Large electric motor. I built a makeshift welder and battery compartment mods and have been swapping car batteries around in this car for recharging to use various tools (electric forge etc…). The car is all repaired up, if unmodified (other then extra car bats), and I should be able to explore around more.
It occurred to me that I should be able to build/heavily modify a better car now, especially since I found a gas station a little south of my shelter. But I am unsure of which engine type to focus on. I was going to stick with electric since I had a functional one already, but I am unsure of how much bigger/heavier I could go, even if I stick another large electric motor in.
I have safe access to a bunch of regular cars though, including some military one (though I think they are diesel), but before I start working on it I figured I would ask for advice here.
I did look on the wiki, and though there are pages pointing to load vs strain, I have yet to actually find any info.
