After the stock water pump kept leaking under the bed, I ended up upgrading to the Shurflo Revolution that you linked. I also relocated it to the very rear lower, driver-side storage compartment. Some pumps are quieter than others, but the real improvement in reducing overall noise was getting out out of the living area. I mounted it using some rubber bushings and you can hardly hear it. Plus, if it ever leaks again, it will be in the exterior (waterproof) storage compartment. The biggest problem with our stock pump was that it was right against the water tank and the winterizing pipe would literally beat it like a drum when it cycled on and off.
I was able to use parts from Home Depot (hose, fittings, etc) and it took just a few hours. I would highly recommend it. Let me know if you would like me to post any pics.
And since you mentioned TVs, I remember that I need to add a sound bar to the overhead bunk TV. The speakers are horrible and even at full volume, its difficult to hear while driving on the highway. I dont care about it, but we have a 5 and 7 year old that would think otherwise :)
