Hey guys, I am new here but have been lurking for a while. I bought this truck used in Nov and have made the mods in my sig to the bone stock truck. The problem I am having is the batteries have died 3 times know over night. The truck is 5 years old so I realize it is probably time for new batteries but I want to figure out exactly what is wrong before I put 2 new batteries in. So my questions are, could it be possible that both batteries are old and just need replaced, or is there other things that I should be looking at that will cause a drain when the truck is sitting over night? I am going to try and get the batteries load tested tomorrow. Any thing else I should check out? By the way this just started happening after my lift was installed 3 weeks ago.
