How to tighten a loose RV bathroom faucet

We have a Fuzion 429. I had noticed that the faucet in our bathroom wiggled a little. So how do you tighten that up?

This turns out to be quite simple but requires some feeling around because it is really hard to see up under your sink. Below is a picture of the underside of our bathroom sink. There is NO way for me to get my head inside the cabinet to get a look at this so I put my phone up in there and snapped a picture.

Notice the two Phillips-style screw heads. These screws are simply meant to push upward against the underside of the sink material. While that entire plate can be turned on the threads that you can see, it is easier to simply turn the screws. As the screws are turned clockwise (righty-tighty, lefty-loosey), they will snug up the faucet. Remember that these screws are upside-down from your point of view, so turn them counter-clockwise. All you have to do is use your fingers to feel for the screw heads, align your Phillips-head screw driver, and turn. There is no need to get them super tight, snug is good enough.
