I replaced the stock pump installed by AS in our 2005 AS LYG MH with the Flojet Sensor VSD 4.5 and have been very happy with it. At low demand, such as when running water through our two stage water purification system, or when running a low flow for washing hands, etc., the pump purrs on and off very softly.
On the other hand, when demand is suddenly high, like when flushing the toilet, the noise level increases. One way to reduce this is to slightly close down the valve leading to the toilet (which, unfortunately, makes for less thorough flushing of TP down into the holding tank).
Anyways, we are having good luck with our Flojet, after 4 years and 17,000 miles of travel, including letting it run dry for four hours straight several weeks ago. (Still functions well, does not seem to have affected it.)
