ABC’s of “Gray, Black & Fresh water traveling?

The questions I’m asking are based on two adults traveling in a 38’ gas motorhome.

Gray 60 gal.
Black 86 gal.
Fresh 75 gal.


• Based on the above information, how long would it reasonably take until the Black tank would need to be emptied?

• I expect that most do not travel will a full tank of Fresh water. But if you’re traveling a long distance, like from Florida to Montana, 2300 miles and 5 days of travel. How much fresh water would be needed for the toilets, dish washing and once a day “quick” showers?

I realize you can dump and add fresh water along the way but I’d think you wouldn’t want to have to do that if you didn’t have to. I’m just trying to get an idea of what to expect?

We used about 14 gallons of fresh water per day, added about 10 gallons to the gray tank each day and about 3 1/2 gallons per day to the black tank.

One shower per day. We alternated taking showers - me one day and her the next and so on.

86 gal black tank??? Wow, I have never heard of a coach (gas or dp) that the black tank is bigger (by a lot) than the gray tank. That's a new one on me.

In any case, I don't anyone can predict what "your" usage would be and therefore can't really provide you with even a good estimate. But with an 86 gal black tank, that should last about a half of a year...., just kidding of course.

You really just need to find out for yourself through experience. However, in my opinion, and with all due respect, I seriously doubt if you have an 86 black tank.

Hi Clay,

OK, that give me 5+ days worth of fresh water and enough room in gray and black to as well. So based on 5 days on the road, you would have a full fresh tank.

Do you adjust the amount of fresh water based on the trip, or do you fill it for every trip?

When boon - docking two of us have gone 6-7 days on typical sized black and gray tanks. But, we've never carried water to our next destination, only filled when we got there if staying multiple days. We didn't like carrying extra weight.

Here's the specification information.

Sorry, I can't figure out how to add the specifications to the post?

We always try and carry full tank of fresh water when we travel. Just never know when you might breakdown in an area and be stranded a couple of days. Might add that I don't see any difference in MPG with tank full or empty.

Hi kketterling,

I was thinking about that too. I would think the MPG difference full water to empty would be hard to read. Thanks

We have 75 gal ea black and grey and traveling much the same( showers etc) and can go about a 6 days . Or more .We have 100 gal fresh and travel with it full , I plan to be prepared in case .... Yes it weighs a lot but the coach already gets lousy mileage .. A tenth won't break the bank and I know I can survive any delay.

Biggest issue with driving with full tanks (water, gray, or black) is the weight added. 100 gallons = 834 pounds if water. Black water may be slightly less (stuff floats).

I get the extra water etc means extra weight. I also like the idea of having the water if you need it! I've read many posts saying they never leave a park without draining the black and gray tanks. That sounds like a good policy to me.

We Full Timed for 7 yrs
We ALWAYS traveled with FULL Fresh water tank (70 gallons)
This is in a 5th wheel and never worried about the added 580#........truck/trailer scaled at 22,500#

We got caught ONE time w/o water when we first hit the road --------wasn't going to happen again

2 adults living in the 5th wheel moving every week
2 grey tanks (50/28 gal) and black tank (50 gal)
Usually had to fill fresh & dump waste tanks at end of 5th day.........then dump/rinse on AM of travel day and top off fresh
