One of the first big things to learn is going to sound really cynical but I feel it is true in many cases!
First thought is to never fully trust an RV dealer to both know what they are doing and to actually do it right!
So that leaves me wondering on a basic point when they gave you a full tank of water???
Did they actually go through a good process to sterilize the new tank, lines, etc. or did they give you a tank that has all kinds of potential junk and polluted water to possibly let your kids get a drink out of the faucet?
Step one of RV is to KNOW that things are done right and that often means DIY!
Step two is to read the directions and make sure before trusting!
So there should be a section in the owners manual telling you how to do a bleach cleaning of the tank, lines, pump, etc. to sterilize for safe to drink.
That is about the only way to know the water is safe to drink! Think what may have grown in a tank with a few inches of water, setting for months in the summer time and not being fully cleaned! YUCK!
Dealer should be shot for setting you up for that surprise!
But moving on to leaks and full tanks? It is not likely the black and grey were actually both full to run over, using the fresh water tank only as it is only a 70 gallon tank trying to fill a 61 and 40 grey and black tank set! There are also overflow drains to underneath on both!
But if the wrong valves were left open, it can certainly leak enough to look like a full blown flood after it runs around a bit!
But to find out what and where, it will go better if you let it dry a bit and check a few valves first before filling the fresh water tank again. It's hard to tell where water is coming from if everything is already wet and RV do have some special tricky things to figure in when looking! Water can leak from a tube, land on a tank and run 6 feet to the side before coming out where we spot it, so be alert for tricks! You may park the RV on a different slope the next day and think you have a different leak as it comes out at a different spot! But that is not a current worry and not too often a problem, just something to mention to keep alert!
One first step to sorting the problem might be to assure the black and grey tank valves are both closed as that is the ONLY connection between the two that should get water from the fresh to them both! For safety, potable water and waste tanks are never connected except where water runs down the drains! Water has to go in the drain to get into the tanks.
When dealing with a new RV, there is a great online site to look over what we have and study things like the plumbing.
An interactive setup that lets you see different sections like drains and turn the RV all around to actually see where the lines run and it is super nice to use combined with the owners manual! The manual may tell you briefly to close a valve---but not fully WHERE that valve is found, under a bed, in an outside compartment or WHERE, so we can look at the drawings to spot the drains and valves!
Big hint when looking? The drains are about the only thing that shows as a tube hanging out the bottom and open, so look back along the line for a valve to open/close!
Click this example to get an idea of what you can learn as it reallly is worth doing the learning curve of how to look around the RV without crawling under!

The drain lines I've marked in red are semi-easy to spot but the valve can be six feet away, so look back along the line for a valve to open! when you click on the valve, it will popup in the list at right to tell you what part you've found or find a part in the list and click it to highlight the item in yellow on the drawing? Lots of good info to sort out where and what you have!
But for the current problem of the black and grey together, it is likely the big main drain valves are open to allow the water to run in one tank and get to the other! Then leaking into the compartments may mean the cap at the oulet is not on tight!
Maybe they were goofy enough to also "GIVE" you a grey tank half full and not close the valves well?
Click for better view!
We can spot which tank is black becasue the stool goes direct into it!
There is a black tank drain and then also a grey tank drain, both of which should be kept closed except to dump.
Then there should be a cap on the output as a final item to keep it all from dripping out in the compartment!
Sounds like both black and grey valves may be open as well as the cap not holding well, so check first??
Giving you tanks with content and sending you down the road without making sure the valves were closed? YUP! Dealers may do that !
