We have a Itasca (Winnebago) with a 90gal water tank and we can go for a week if we are careful .

Depends on many things, one obviously is how big the tank is and another is how efficiently you can shower and your general water conservation habits. As a general rule I allow about 5 gallons per person per day (with very careful usage.)

With conservation, yes it should last 3 days.


Use paper plates and plastic utensils that can be tossed.

Shower - get in wet down, turn off, soap up, turn on and rinse off - get out. Wet down is not standing for a few minutes, but just wetting down.

Water is definitely needed to flush, but this is not the time to stand on the pedal for long times. Also, using the "outhouse" saves water.

Yes, it can be done.

We have a 100 gallon tank and easily manage 2 weeks for the two of us boondocking. A lot depends on conservation, but 3 days should be no problem. Just don't let the tap run and practice basic conservation (short showers, short washing up etc.)

If you want tips on conservation here are some of the ones we use:

We have gone for three days with 4 people (wife and I plus 2 daughters) doing volunteer construction work. Short camp showers and a very low flow shower head do help. On some class A coaches it won't be the 100 gallon fresh tank but those with only a 40 gallon grey tank that will be the limiting factor.

We use about 12 gallons of water per day. We take navy showers on alternating days - I one day and she the next. Other than the navy showers we are not excessively careful with how much we use.

We just finished a 7 day boondocking trip. 75 gal tank and the tank indicator had dropped past 1/3 while breaking camp. I'm figuring we could make it 10 days being ultra conservative.

I dunno....
We shower every day. We wash our dishes. Me and #1 son, last year at chicagoland speedway, filled the black tank on the fourth day.

Really tho, you never know. we have a techma electric toilet, and oddly, our black tank fills first. I guess this toilet uses alot of water.

We (2 adults) cook, shower, toilets every day and can go 6 days on a 100 gal tank with 1 day reserve which is normally for the 40 gal black tank which needs help first. We haven't tried reducing the water useage in the toilet for feer of the "stack" while sitting boondocked.
We drink bottled water and share flushes 2-3 times per day sometimes.

My 40 gal tank tank lasts me 2 weeks with extremely judicious water usage. Fortunately I have a 50 gal holding tank so I don't have to worry much about that.

I'd ask how many people? How many are young kids? And are there any teenage girls with long hair. Our fresh water tank will carry my wife and I for well over a week unless we have young kids (the boys like to watch the water flow down the toilet) or teenage grand daughter with long hair (wash & rinse then wash & rinse and then some other chemical & rinse). All that said I'd think you'd be good for the three days but for a three day boon docking trip you probably are not really remote and could go somewhere and take on water if need be. My suggestion is to have a few drinking water bottles extra in case you do run out.
