Came back from a camping trip. Left the Travel Trailer hooked up. While it was being cleaned I guess a interior light got left on and drained both my batteries completely. Any ideas? Just jump it and let it recharge? Or should I bite the bullet and replace one for now? I Don't use it as a daily driver, it's a '18 2500 Tradesman

unfortunately you should/need to replace both at the same time with the way the Cummins batteries are wired in parallel to each other.
If your wanting to be on the frugal side, give the batteries a good charge and check to see how they do.

If they are not too old charge them up. I would also load test them after a good charge.

Thanks for the replies folks. I have the driver side battery on a charger atm. And I will switch over to passenger side next.

Have had my Ram 2500 since August of 2019. Today my batteries finnaly kicked the bucket. Question for you all is the 3 year mark normal for the batteries to be replaced. Thanks all.

Unfortunately yes 3-5 years is about all you can get out of them now days. Must be something to do with how they are built now. I remember that 8-10 years was not hard to get out of a battery.

I got just shy 13 years from OEM 2006 Dodge CTD batteries, they were still good when taken out, did not want to chance them on the long road trip.

That's funny, I'm still on the original 6 year old batteries in my 2017 CTD.
