Newbie with a leak

[Jendaya]

Hey all I just bought a 2005 Keystone Montana 3400 r l

We have a leak somewhere but weren't sure what the source is. It is saturating the carpet in front of the fireplace and is leaking near the water heater components by the back tire below outside the water is dripping outside. Please suggest any repairs that will help!

I looked at the floor plan on line. It looks like the fireplace is in the slide and that the water heater is right in front of that by the tires. I would check is the roof. Check all to caulking on the entire roof for any questionable spots. Clean them and use Dicor self leveling lap sealant. If you have filled the water tank, or used hooked to city water, and filled the water heater, you may also have a leak in a pipe or connection leading to or from the water heater. Could also be the water heater itself.

There are a few things to look into.

All of the above make sense. If you can't find a leak above or if the water is dripping when it's not raining I'd take the wall out in the basement and see if it's the water heater. We just replaced the one in our 2017 so they don't necessarily last all that long.
