But I also noticed that GM has changed their towing recommendations for PU's. Still towable but you must disconnect the neg. battery cable. Not only is that a PIA but those with portable brake systems will not be able to use the cig. lighter plug! What will happen to your radio settings? I wonder why you have to remove a battery cable?

I was replying to the above - using my smart car as an example. With the extensive electronics in newer vehicles these days, not following the towing instructions can become very costly. In my case I copied the flat towing instructions right out of the owners manual, made a checklist and laminated it. I follow it to the letter because if I burn the engine and transmission then their replacement will cost more than the car.
I use a battery disconnect switch as instructed in my owners manual. Every time I tow the radio loses its settings. Maybe an aftermarket radio with permanent station memory would be better, but my solution is to always set the radio to AUX, plug my smart phone in and listen to my own commercial-free music. I don't bother with programming the radio anymore.
