Please help with batteries dying.

Tgats just clearly a dead battery set/alternator issue

MAYBE the fridge sped it along, but my cooler will keep at 40 degrees in full summer for 48 hrs on a 3 battery setup before its hard to start, so a 10 hr should absolutely NOT kill starting capabilities

 

Loves tested the batteries, but did not check the connection. Hmmm…


(You people contemplating buying a truck, you want to pay attention to things like this. Every time you take the truck to a shop, they’re going to try to get you for $1000. You want to be able to diagnose and fix as much as you possibly can. Especially when it comes to the electrical and wiring. )
