I would be too. 3 reviews and 2 had case leaks within a few days.
That G9020-47031 is a toyota part number, so for anybody wanting to buy a pump like this, but with better reviews you can use that number.
Good find though, it's a brushless dc motor with the magnet on the impeller. So that means no shaft seals to leak. It isn't self priming though so you'll have to have the water level above the pump.

or a foot valve similar in function to the ones used in domestic water systems with wells as the water source - once primed, it would work fine

For cold water use I don’t see this part failing unless it’s defective from the manufacturer. The temperatures and pressures they’re designed to operate in are well above those encountered as a skoolie pump. These typically run 100,000 miles as a coolant pump on Toyota Prius which I have some extensive experience with. Definitely buy the better rated one if it makes you feel better. I’ll post updates on my build if there are any issues. Which I’m sure there will be.

At that point, you can spend an extra $15 and get a self-priming ShurFlo pump and be done with it. It may use some more power, but unless you're using a lot of water, this is fine in most cases.

another case of where a condemned camper or trailer would have some useful parts, including a pump and holding tanks

Neat find! I have an application for just such a 12v pump. I don't want the noise of a diaphragm style RV pump and it's for a closed loop so I don't need it to be self priming.
Another nice feature is that it can be fully submersed.
I think even that cheapo one with bad reviews would work fine for my use. The complaints are about it leaking at the seam which some caulking or JB weld could cure right quick.
Alternatively I may poke around some junk yards for a Prius!

My point exactly. This would be great for a tub or hot water application too.

The good ol' SHURflo 2088 is still the simplest and most reliable pump out there, and if it's mounted on a resilient pad it won't make as much noise. I have two of them under the floor next to one of the tanks, and when it's running I can't hear it inside the bus at all.
