33gal freshwater, about how long will it last?

Try this before you go. Fill your freshwater tank. Find a container to run water into. Time how long it takes to run out of water. Now you will know how many minutes of pump running you have with a full tank. And if you use a container of a known volume you can also see how much usable supply you have.

We use the camp showers and wash dishes with the campground water spigots as supply water then dump after dishes are done.

Some parks do not allow washing dishes at the hydrants. Too many rinse off garbage which smells and attracts insects.

My KZ had a 40 gallon tank. About half of the water spilled out the vent pipes and the bottom 10 gallons was below the supply port. I had about 10 gallons of useable water after driving 80 miles. I completely changed the entire "system". You should measure the amount that you can use before depending on it.

our 20 gallon lasts for 8 day trips without becoming fully empty. We only use it for toilet flushes and hand washing. We bring a couple small bottles of water from home for drinking / coffee / tea (we are on a well and HATE HATE HATE the taste of chlorine treated water)

My kids and I could get 3-4 days out of our 50 gal tank with some left over. When my wife comes along, we're lucky to get through the second day. She's constantly washing her hands, or scrubbing this or that. I love camping with her, IF we have hookups. Boondocking results in arguments. She looks at me like I'm crazy when I suggest she doesn't need to keep washing each and every thing. THAT'S why people can't give you a good idea how long your water will last. I've done things to stretch it, like bringing a couple 6 gal water containers, replacing the shower head with an oxygenics, and using a wash tub in the kitchen, which then gets emptied into the toilet, saving gray water capacity.

I will give you my needs.I can comfortably go 5 days on 26 gallons.I carry bottled water that I use for cooking generally 2 gallons.The tank water is for showers,washing dishes etc.Do not have an animal.All my camping is done at National Forest campgrounds, most do not have potable water availability.

my wife and i used about half of our 30 gallon tank on our last 4 day trip and we made no effort at all to conserve water.we were testing the limits to see how long the water/battery would last.

For us its about 10 gal per day with washing dishes, a few toilet flushes and occasional navy shower. We only have a 30 gal tank so I have a 6 gal container for refills.

Maybe a stupid question, but why are black water and gray water tanks separate? Why not just 1 larger tank for both? I'm sure there's an obvious/important reason, but our homes/sewers handle both, so why not just a "waste water" tank?

nevermind, found another thread with this topic

Another case where people offer an opinion without all the facts. The first thing to do is to determine how much water is actually available. (Fill some buckets in the shower/tub to verify) I have had some rated at forty gallons that sputtered out after twenty five. After that, one can make estimates based on five gallon per shower, etc.
