I haven't done much electrical wise in my new suv and came across so unexpected money. I was wondering should I take the money and by two maybe 3 batteries or buy a quality h/o alt. I'm still running the sundown 2500d. If I buy batteries I plan on running an xs d925 under the hood and an xs d3400 in the back. Thanks guys

both ... but I'd start out with the alternator because the stock one might have troubles charging the new battery bank ... and I'd stick with 3 batteries if possible.

 

Just my suggestions here brother !!!

thanks for the input! i'm definitely doing both just don't have the funds for both right now

Then I would def. get your upgraded alternator and Big 3 done first ...

did the big 3 the first day!

Both batteries and H.O. Alt.

Alt first! This way your stock alt wouldn't struggle to charge the batt bank.

Do you have second batt right now?

All I currently have is the big 3 done, everything else is stock

Both batteries and H.O. Alt.

 as previously stated I will be doing both but I don't have the money do do both so I have to do one or the other first
