Just off, the 1951 Chevy Pickup would have a curb weight of 3200lbs or so. I found several different numbers. Looks like some of the hot rodders have put aluminum beds on them for weight savings.
Also most of the older stuff will be rear wheel drive. That has to make things less complicated right? Maybe lets me put a little bit of battery weight on the front axle. An in-bed truck box for weather proof battery storage. It's an interesting idea.
That does bring to mind another question. Towing with an EV.
Now clearly electric motors can handle much higher weights/loads and voltages than they were designed for. A number of people have proven that. It's also obvious that towing is going to drastically affect range. Other parts of the equation match with gas-towing. Brake and tire wear in particular. Transmission if you have one.
I know electric "city trucks" have been around a while and can remember hearing about electric fleet vehicles in the 70s.
Plenty of torque available. What affect would towing have on an electric motor? Or an EV in total aside from the obvious range/brakes/tires/transmission bit?
