If you have PEX pipe in the RV and you don't have a cheap filter canister, you should be OK with the little Vlair.
FWIW I have the older air pump system and the fresh water tank is pressurized to push water rather than a pump drawing from the tank. There is a Schrader valve on the fill cap on the exterior. There is also a pressure gauge in this cap. I start my construction grade Hitachi and pressure the tank and system. My pex supply lines are all new, BTW.
I start at the furthest fixture, the bathroom sink, and open that valve. I only have the toilet, shower, and the Kitchen sink after this. Last time, I shuffled back outside to the fill cap and it read 90 psi. That was unexpected but it was a good test for my new plumbing.
You need volume to blow out water lines properly, you have the volume with your system. There is no volume with the compressor the OP is asking about.
