I've read 8000 pounds and I've read less. Really depends on your shear pin. Factory shear pin goes above 8000 lbs before it breaks in my experience. But it eventually does. And then you get out the snatch block and do a double line...
Yea that's ultimate efficiency. Wiring would be cheap as hell and easy to handle. Going from 4-6 gauge to maybe 10-12 gauge for long runs.
However, going 48v makes the whole system a bit larger, all appliance or things you would use off the system are either 12v or 24v, so that's extra step-down converters you have to wire in and make room for. As for solar, you would need to make sure you could get a high enough voltage to actually charge the system, which may be issues in a mobile vehicle setup with room constraints.
Can be done though, interest to see more tinkering like that.

Check your air conditioner's harmonic balancer sometimes called pulley B.
Just before a 2k km trip I happened to find quite by accident that it had separated and the heavy steel pulley was a fingers width from flying off and doing who knows what to my engine compartment.
This is a rubber insulated pulley like the main harmonic balancer. And also like the main balancer, it wears over time.
This was mine after I unbolted the balancer and reunited it with its pulley:
Apparently the cruiser gods were smiling. Except when my trip saw temps of 38°c lol. But after I got back the new part arrived and is now in. Cold A/C again... And some sense of relief that that was the only casualty.
