A few owners have moved the compressor into an outside compartment to get it out of the weather. When they are mounted towards the rear axle, they susceptible to splashing and road debris.
If the compressor still cycle on/off for a short period of time, it's likely it's plumbed wrong. Monaco plumbed many of the coaches with the compressor up front (windsor, camelots, some beavers) incorrectly. It's a pretty easy fix and has good results.
