Access under sink

[NC popup]

I have a 2015 Flagstaff classic popup. On 2 occasions there has been a small puddle of water on the floor near the sink. How do you access the plumbing closest to the floor?

We had a small leak in our new unit (not the same) and it turned out that the fitting inside the sink was a bit loose. Fixed just by grasping and rotating the "nut" underneath the sink tight again.

I know that doesn't answer your question, but it is something to look at.

GAWade, thank you for your response. All the plumbing we can access easily via the cabinetry is dry. We thought that it was due to not using a pressure regulator the first time it happened. We quickly installed a pressure regulator and did not have the problem again, even on the next week long camping trip. A small puddle formed on this last trip. I don't know how to get to the plumbing closest to the floor, no access via cabinet doors and when you drop down the sink, no access there either.
