Default Installing a Ladder Line to the house

But if I run a long coax to the same antenna, I
would prefer to keep the tuner at the same place, in
front of the short 10 ft piece, and then run my long
cable from the radio to the tuner, which is still at
the car.

When the SWR is not 1:1 but is of a reasonable value:
A short coax run is usually low-loss. A long coax run
is usually not low-loss. When the tuner is located at
the transmitter, the near-conjugate match at the
antenna can only be achieved in a low-loss system.
Open-wire HF transmission line systems are usually
low-loss systems.
