Did a quick google search, can't find anything about Pronto. Looking at your profile pic I see it's a Class C.
It should have separate coach and chassis batteries and an inverter to charge them.
An inverter will also supply power to all of your 12 volt lights and accessories.
As far as how well it drives, I suppose it's like any other vehicle, depends on how well it's been maintained.
Are you planning on taking her out for a trip?
