Hey guys i appreciate all the response and comments. I apologize for the lack of forum decor. i don't get get much time on the computer. Im not looking to make a quick buck, and im not even asking for a dime. I just made something that has been working on my truck, and some friends and relatives. And i would just love to get feed back from anyone willing to try. I have tested these on a few different trucks, dodge, ford, and now silverados. Just looking for people to give them a shot on their trucks in different climates, driving styles etc... its just fun for me, and yes, if i could make a buck or two great. but this isn't some mega company looking for guinea pigs. just me and my years of experience looking for ways to occupy some time. Did i mention they were free? lol
