Don't buy a cheap one! They sound like someone is using a jack hammer inside the trailer. Ask me how I know.

There are several types of RV water pumps that will work. A 2.9 to 4.0 GPM with a 50 to 55 psi is usually recommended. You can get a Shurflo or a Flojet, in a little better model and be sufficient. The Flojet model Triplex pump is a good one that is quiet and has rubber mounts, it is less expensive as well. You might check with a local RV Dealer's parts catalog and pick out one you like. Good luck! HD.

Has anyone used the Flojet R4514-743? This is a variable speed pump, no pressure valve, no cycling. It's more expensive but not all that much

Flojet's unique Variable Speed Drive system needs no pressure switch. Its microprocessor provides precise speed control to match the system demand. As more water is needed, the motor drives the pump for more flow. As the demand lessens, the motor slows to a super-quiet speed, yet maintains a steady pressure. The result is an unbelievably home-like flow. This smooth performance from no flow to maximum flow is sensor controlled, without any cycling - so an accumulator tank is not needed. The system is free of pulsation, water hammer and temperature swings. Amp draw reduces as flow reduces to conserve energy, ranging from less than 1 amp to a max.of 10 amps. Self priming up to 10'.Automatically adjusts to 12V or 24V input. Thermal overload protection with auto restart. USA

A friend put one in his '87, 31'. It is nice enough, but (my opinion here) I don't think it is all that much better than the simple on and off flojet alternative, which is less than 1/3 rd of the price.
