you will only be able to drive as long as your battery can live, which will probably only be an hour or two max(every time you use something electrical, like windows, blinkers, lights, or the radio it will shorten that time too, as well as every time you start the truck -that will really shorten the drive time.)
Nah, just do like I do with my lawn tractor. Stay close to home, don't run it for more than two hours, and put it on a charger when you're done. Problem solved.
Good point!! I ran my originals for 120K and they are still in my trail spares box. They look like they have another 50k in them, at least. Over-tightened? Maybe seized alt? Spill anything nasty on it?
