Well, my wife and I will soon be celebrating our 4 year anniversary and I just bought her gift. We set our limit at $100. I GOTTA add a mod to the Tundra, but not sure what direction to go for only $100. Suggestions? I'd like to add an inverter, but I really have no need for one right now and this time (unlike in my 4Runner), I would like to add a true sine wave inverter which is a lot bigger and a lot more expensive. One day, after we have kids, I will add a rear seat entertainment system. Give me some ideas fellows so she can get it (whatever it is) on order Thanks!
