New Ram owner here. Been reading everything i can for the last 3 weeks. Ive only owned the truck for 3 weeks and love it more every time i drive it. So i am looking to install a overhead gauge POD behind my mirror. I am debating on just a two gauge or go ahead and put in a 3 gauge one. I will be towing a sizable trailer so a transmission temp gauge is for sure. After a transmission temp gauge what would be the 2nd most important gauge to get?????? If i go with a 3 gauge POD which 3 gauges do you guys reccomend ???. My truck is a mostly stock 2004.5 3500 4x4, 3.73 gears ,48RE, stock except a S&B cold air intake and 4in exhaust. thanks in advance Scott
