Im going to start with the side camera system they offer. You only need to drill through the cladding on each side of the camera—shorter routing for the hose.
I'm definitely sold on the side cameras. Drilling in the steel and routing it all the way to the back is concerning. I have both kits; I haven't installed either.
Grok says the A23 sometimes works, sometimes doesn't, depending on the circumstances. I purchased the smallest jump pack I could find and will figure out a way to secure it outside on the truck.
When I went through the process, I was told it was only for CTs in inventory. I found one that required me to fly and drive before December 31. However, my brother got the same stick as you. If he wants it now, he needs to pay the new price.
In 2025, you can't dismiss the fact that Elons assignment with DOGE hurts the CT the most out of all the Tesla vehicles. If they can figure out a way to get the AWD down another 5-10k, I think it would be a contender for the next couple of years.
