Jump box for dual battery 7.3 diesel
I started thinking about items I might need as a new RV’r, jump boxes came to mind. I’ve looked at a few video’s online of large diesels requiring higher amperage jump boxes when their batteries are ...

A jump box big enough to start your 7.3L diesel on its own is going to be a pretty healthy and costly jump box. Probably about 3000+ Amps. Like all devices with their own batteries, the batteries can either last a good long time if you’re conscientious about maintaining them, or they can have a short life if you neglect or abuse them.
For my use, instead of buying a jump box big enough to start the truck engine, and likely not get used for much else, I bought one big enough to start the built-in Generac in my camper even if it’s less than 100% charged.
I’ve got a NOCO GB40, and I use it to recharge USB devices primarily when we’re off-grid. That way it sees some use often enough that I know it’s state of charge. The chances of ever needing it to start the generator are pretty slim, but id never say impossible. I also don’t totally trust all this auto-magic BS on modern vehicles that’s supposed to keep the battery from EVER getting flattened. I occasionally get pretty far away from help, and like to have several backup plans available. Stuff like that always works perfectly for me.......until it doesn’t.
So, my advice would be to think about where you’re likely to be and what other equipment you will have with you, and how you’ll use it to help yourself if the worst happens.
