Question:

Installing disc brakes on a fifth wheel RV and would like to know what you think about attaching the brake lines directly to the axles to cross from the main line side of the trailer to the other side.

I believe what you mentioned is a standard way of running trailer brake lines on a tandem trailer. I attached a diagram for the brake line kit part # 18TA-BLKIT and how it normally connects to a trailer. The main feed line runs to the first axle where a Tee splits it off to run to either assembly on the axle. These lines attach directly to the axle.
