Water storage up top

Guys, I looked for an answer and can't seem to find one. I'd like to have water tank on top of my van over the cab. 20+ gal. would be nice and I'd like it to have a hose for washing stuff off and maybe even taking showers from. Any ideas?

thats over 150 lbs of weight way up high. bad idea. if you want to wash stuff off put the tank down low and use a pump

I already considered that. There's no where inside to put it and every single time I've ever stored water inside, the padding is soaked in no time and I'm dealing with mildew.

I should have posted a pic. I want it to go on the rack above the cab.

H2O is high density: 8.8lb/gal and 7.8 gal/ft3=68.64lb/ft3. 20 gal=176lb. Placing heavy mass on top raises your center of gravity. In a collision, a container of water flying off the top would act like a cannon ball. How about storing it down low, but when you need it, just hoist a 5 gal jug up to the top temporarily, use it, take it back down?

Of course, storing it low and center is optimum but I'm leaving in 10 days and don't have the luxury of fabbing anything up. We're going to be camping on beaches and hiking in the desert alot and a ready supply of gray water is going to be a must.

Maybe I'm trying too hard. What about using a couple of those 7gal blue tanks from Wal-Mart? Anyone know of a good way to use a small hose with them?

Just go get the 7 gal jugs for now and you can visit an RV shop (I know there are some in Socal) and get a 12v pump and showerhead combo that has a button for shutoff.
Or if you want how water showers go get a stainless bug sprayer and swap out the head for a rotating garden one with on/off handle. That will let you warm water on the stove and mix in the sprayer for a quick & easy shower/dishwasher

I'd suggest the 5 gallon scepter-like water cans from LCI. Here is thread with the link to buy them and instructions on how to tap the spout to add a hose.

Do a guest login, search on "water can". Right now it looks like they only have tan and green.

Here's what I did.

This is to maybe give you another idea. These Rotopax containers are 4 gallons each and they have several mounts available. As long as they are full, I don't notice the added weight up high. I carry 4 gallons fuel and 4 gallons of water here. I also have a 5 gallon on the back and 12 gallons inside the camper.
Hope this helps.

Doesn't need to be potable? How about ABS pipe with end caps cemented on? You could plumb in an inlet and an outlet with materials from Home Depot. Black would absorb sunlight, and keep it warm.

1 cu ft = 7.5 gal, so 4" pipe holds about 2 gallons per 3 feet of pipe. A double-pipe, full-width tank on your roof would hold around 7-8 gallons.

Geez, it's not like he's permanently mounting these water tanks up there. You've never carried more than 150lbs on a roofrack?

I'm likewise struggling with the importance of center of gravity. I agree - low and center is great. But in this case, 20 gal. strapped to the roof deck and plumbed would be amazingly cool.

And as far as weight, the center of gravity on a SMB is much, much higher than my rig by simple virtue of the hardtop.

Why would you need to carry that much 'grey water'? Don't you mean fresh water? Grey water is waste soapy water (from the sink or shower waste)
