Ok, let's calm down... everyone is entitled to their opinions and thoughts. Your TV may or may not accept the additional lighting load. Check with Jayco to see if the frame on your TT will accept the additional trailer.
I would hate to be on the road and all your lights go out. Carry a bunch of EXTRA fuses with you. I have seen a few setups like this and the driver was inexperienced or the setup had a problem as the boat was swaying back and forth.
They make units that interface between the TV and TT that uses the main 12Volt supply from the TV and through electronics it sends the voltage to the trailer's lights, brakes, turn signals.
Just drive safely.
