When I bought my Silverado, it came with 6 months of OnStar and my wife bought minutes for the phone part of it. The phone part worked great for me. Never had any issues with dropped calls. No one ever complained about being able to hear me and every thing sounded loud and clear in the truck. I did drop OnStar after the 6 months was up. I didn't use it often enough to justify paying for it. No complaints for me other than the price.
I've told my kids many times that they would not have survived my childhood. We had to go outside!!! Can you believe that? We would play with and actually talk to the other kids in the neighborhood. We couldn't text, facebook, or call them on our cell phone. We didn't come home until mom was calling us for dinner. She didn't call us on a phone either, she stuck her head out the front door and yelled for us. If we were thirsty, we didn't go to the fridge and get a Gatorade or energy drink. We had to drink out of the lead infested illness causing water hose. How horrible. Every time I hear one of our kids say "I'm bored", I go off. They have no idea how good their spoiled little butts have it. All in all though, I'm glad I grew up when I did. I wouldn't trade the lessons I learned for nothing.
I use 2 Zip Lock bags (gallon size). Slide them over the business end of the bars and slide them in the pass through compartment. The hitch head stays on the truck unless we are going to take the truck out somewhere, then it goes in the pass through too. While in storage, it all goes in the pass through.
