The current is the current of only one panel, while the voltage increases with more panels (I have 4 panels, at more than 80 volts).

With only about 6A running through the long solar wires, even 12 AWG will have very little power loss. So, you can run from the front shell (down a lift arm, NO PIERCINGS!) and then clamp your solar wires to the underside of the TM, entering the battery compartment (where the MPPT controller is) from underneath. An actual entry box might be more waterproof than running just the cables and smearing them with 3M boat sealant.

2 panels is hardly worth the trouble, you should get at least a third.
