Haha! Yeah, my towing duties are nothing compared to yours. LOL!

Still I need to get the hitch on my Silverado so I don't have to ask to borrow my wife's ride every time I need to tow something.

Mine is a 3 way switch so I can control my front and rear camera while on the move.

Pretty much. I was looking at a latching LED push button but yours looks pretty good. I take it you had to clearance the back of the cover for it?

Oh snap. I didn't even notice what looks like porcelain missing from around the electrode.

Either detonation or too high of temperatures. That buildup could lead to hotspots, which could lead to overheating of the plug and/or detonation.

Looked like it to me at least. The deposits on the ground strap are suspect and that black electrode looks like flame going in the wrong direction.

Think I took my NBS to Walmart and had them throw in their brand battery for like $80.

I've bought two of their MAXX start or whatever model battery in the last year. at around $90 after core and 5-year free replacement, it was a no brainer.

That is a smart idea, and I've done that before with other vehicles. However, this is the nicest rig I've ever owned, and I'd hate to mess it up, or to get in there to only realize it was worse than it initially appeared, and it end up costing more money and time. That's obviously an excuse, but I'm still in the mindset of "you did this, you make it right!", without me having to spend my time on it. Although, a few hundred bucks would be nice to have this time of year.

Do it. Crawl under there and if the bumper bar isn't bent and your back up sensors work, you should be good. The lowest and most rearward piece of metal under mine is the hitch and then the bumper bar. The Hyundai that hit me got the hitch with his radiator tank... the hitch won obviously. Nevertheless, there's not much back there to get messed up by a car basically submarining the rear of your truck.

Honestly... I'm not really sure what you guys mean by detonation or too high of temps. Just not that well versed in the technical stuff. When you say overheating do you mean overall engine temp? For example I had my coolant hose that runs back to the firewall blow out not to long ago which had me climbing in the hood of my car in the middle of the parking lot fixing it. But I am pretty sure I dumped all the coolant out of the car that day and temps got pretty damn hot. Is there something else I should be looking at here? Thanks for any help or direction you can provide.

High temps couldn't have been good for it as too much heat in the head would make it more susceptible to detonation (pre-ignition of the air/fuel mix in the combustion chamber, the reason for knock sensors). I would suggest making sure you're running good gas, cleaning up your air/fuel mix components (anything effecting air, fuel, or air/fuel ratio measurement and make sure you're running the right plug at the proper gap. If you've got everything in those areas squared away, there could be a more specific problem. Not trying to say there's cause for alarm but, I'm just the type that I'd want to try and rule out any significant issue(s).
