I got a 2023 Model X in December. A couple of days ago I decided to test it's ability to tow our RV and see how the range would be affected with our particular trailer. Well I couldn't get the Prodigy RF brake controller to work. Turns out the problem is that this particular brake controller needs a live 12V feed. As I see it I'm now faced with two choices and I'd like this community's input on which way I should go.
First would be to do the 12v mod (presuming I can on the 2023 model) and continue with my Prodigy RF brake controller. The advantages are (1) cheaper, (2) I like the controller not having to be permanently mounted to the cockpit of the vehicle, and (3) have a 12V feed for any other applications where this might be useful.
Cons are (1) possibly prematurely wearing out the 12V battery of the X, (2) possibly increased hit to the Model X's range when towing, (3) voiding Tesla's warranty, and (4) while I'm slightly above average in tinkering with things, I'm not keen on doing it with such an expensive vehicle with potentially catastrophic consequences if I screw things up. Not sure about whether or not possibilities 1 to 3 are valid concerns, would appreciate feedback on these.
Alternatively I could ditch the Prodigy RF brake controller and install a Prodigy P2/P3 controller. Pros/cons are the opposite of above. Although activating the 12V supply on the X is cheaper, the cost of a P2/P3 is probably the least of my concerns.
Any advice would be much appreciated. Thanks in advance!
