Water pump replacement

Question

I need to replace the water pump in my Challenger fiver. In doing a search here, the SureFlo 4008 Revolution seems to be a popular choice. However, some say the Remco Aquajet is the way to go. It's also double to price.
I dry camp about 50% of the time and use city water the other 50%. I have an accumulator already installed.
Recommendations?

Iused the Revolution and it is quiet and works fine for my needs.

I have the Revolution in my new TT. It's quiet and works "OK" but the water flow isn't completley smooth and the pressure isn't great.
I'm used to my old Sensor 5.7 though, which will go on this trailer when my warranty is up.
(I have the only good 5.7 they ever made)

All of the variable speed pumps seem to have issues because of the electronics involved.  The "Revolution" pumps are either off or on and vary the output with an internal bypass. IMO, that's a much more reliable system.

Hot enough to cause a fire.  I know this because it happened to me.The only "good" 5.7's were the very first ones.  They lost their original electronics supplier and it was "downhill" from there.

It' has worked great for 13 years though. I've even accidentally let it run dry for a couple of days on two occasions and it still works perfectly.I guess I got lucky!
