To the OP I just completed an install like you were asking. I have 2 Lifeline GPL-4CT 6 volt batteries. I installed a gopower 1500 watt pure sine wave inverter . The cables were 1/0 for all my cables. A total length of the positive cable was 1ft fro...
Bummer....I have the same truck only a 2500. I was planning on switching to the 275 size because of the greater selection of available tires. Is yours a 4wheel drive?Yes mine is 12 SRW CC 4x4 Diesel Shortbed.
I have 2012 3500 SRW and run the original 265 70 R18 most of the year. But I also have 275 70 R18 winter tires. My 275's rub the plastic wheel well behind the front tires if I turn sharply. My winter tires are studded Coopers. Hope this helps.
