Working with wiring in conduits which we typically do not find in low voltage (12V) automotive circuits and most RV’s, when a shorted or broken wire is difficult to locate after spending reasonable time and effort, it can in some cases make more sense to abandon a problem wire(s) or section and run new wire(s), even if splicing a new section in to take the place of a faulty section. Splicing of course would or should not be done in conduits. Pulling the bad wires out and replacing them in conduit, or correcting the fault if in a junction box is the best approach. And too, 120V wiring in RV’s if spliced, a junction box should be added at each splice point where the new wiring connections are made.

Excellent article (as usual). I would only add that I've always seen it spelled Occam.
