Neal,
Here is a link to the Aqua Jet 5 chamber pump I recently installed in our 2006 Diplomat. The problem with this pump is it is larger than your OEM pump and most likely will not fit in the same location.

Here are some things you can do to reduce noise in your existing system.
Most of the pump noise is actually water hammer caused by the movement of the PEX water lines thru out the chassis. The first thing to do is add flexible lines to the output and input of your existing water pump. When the water pump operates it vibrates back and forth and the hard connections between the pump and the PEX water lines transmit the vibration to the water lines. You can usually purchase these flexible lines in home supply stores in the plumbing section. They are most commonly used in sink and toilet installations. It is best to get them long enough so a loop can be formed in the connection.
Another trick is to purchase pipe insulation that is split and push the insulation on as many of the PEX lines as you can get to. Often the hot and cold lines are routed together and have the tendency to bang together when the pump is running.
Over the years I have tried to improve on the OEM mounts on water pumps with little success. The problem is that the factory often mounts the pumps on a surface that acts as a sounding board. The pump on our coach was originally mounted in a vertical position to the compartment wall. I did not see any way to improve on that and choose to relocate the new pump on the ceiling of the compartment.
Good luck on your quest for pump silence,
