Replacement Water Inlet?

I've replaced them in the past, pretty easy, the better ones are made of brass as I recall. Check the end inside the trailer, some are male and some female. Thread size is the same on all I've seen.

I ended up ordering a couple on Amazon. $27 for both with free shipping. They look very similar to what I have. It's lasted 4 years so I figured they are easy enough to replace if it fails again.

Thanks.

We replaced ours last year. Turned out there are a variety of different ones so be sure to get a replacement that's right for you. We replaced ours because the internal check valve failed and being internal to the valve assembly, could not be purchased separately the installed into our assemble.

Replacement was easy but putty tape will be needed to assure a leak free job. We also overlay the putty with a thin white caulk as added insurance.

If you're talking about the city water connection, I'm looking to replace mine for the same reason. I haven't seen this one in person but it appears to be a better alternative by simply having the brass check valve instead of a plastic one:
