Well, today just sucks!! I was suppose to go wheeling today in our first group run, and when I go out to the truck this morning, it won't start; the battery is dead. I need to get a new one ASAP, and I want to get an Optima, however, I don't know which one. Currently, I have 4 sets of auxilary lights and a compressor running off the battery. A small stereo system is in line, but that's probably it. Which would be best for my application, the red top 34R or the yellow top? If the yellow top, what's the model number? And I don't mind spending the extra money to get the one that fits the truck with having to extend the power and ground wires.
