Great choice! I am sure that you will be very happy with the new truck. I sure love my new Tahoe, even though I have had it since July. I turned over 2K miles this week.
The only tip is to check the fuse box under the hood for the 12v fuse that will "power" your plug at the bumper. Take a look at this and it should help you figure it out...

Other than that, I am sure it will make a very nice TV for you.
