Jayco, like nearly all manufacturers have gone with the "central utilities compartment" concept where potable connection, black tank flush connection, dump valves, and even CATV connections are all in a single location on the trailer. Only downside I see is if the mechanical linkage to the dump valves is rather long, it might be frustrating to service or repair. Other than that, it seems like a good idea. On our WhiteHawk, the systems are not as sophisticated, but all the plumbing stuff with the exception of the low point and fresh water tank drain are located on the same side of the trailer and close to one another. Simple is good too.................
