I believe my Gray tank capacity is about 33 gallons for the shower and bathroom sink. I have a separate tank for the kitchen sink. We started with an empty tank on Friday morning and brushed our teeth morning & night and took a total of 4 showers and this morning (Sunday) while showering (5th shower) ran out of capacity. Does this sound right? I new at this and trying to learn my limitations.
Thanks,

Lenny

Depends on your level of “Navy” showers. I catch what I can when showering for toilet flushing but I’m almost strictly a boondocker.

You're lucky to get that far, even using the "navy shower" method.

Like jdc1 said.... even at military showers, the capacity fills quickly with 4 showers..

If you were hooked to 'city water' for your water source, then yes... You filled the tank.. 30 gallons ain't much!

No sewer hookup in your campsite?

Can't run the water like you do at home with no sewer in the campsite..

Now you know! [emoticon]

Good luck! Mitch

It’s amazing how little water you can use and still stay clean and brushed as well as wash dishes.

If we're staying at a state campground with showers I use them and let the wife use the RV shower. We can last a week like that and using paper plates and grilling.

You don't say whether or not you're in a full hook-up site. When we are, we leave our gray tank valve open. Solves the problem of having to dump ever couple of days. I close it a day or so before we leave so I'll have a good water flow to flush out the hose after draining the black tank.

When we're not on full hookup sites, my wife and I can squeeze out a week with alternate day navy showers with "spit baths" in between. We have a 65 gallon fresh water tank and the grey and black are both 27 gallons. One "trick" we use when necessary, since the black tank normally fills much slower than the grey tank, is that I installed a third master drain valve that we can keep closed while opening both the grey and black valves, combining the capacities.

My wife and I could squeeze out a 3 day / 2 night weekend on a 33 gallon gray tank. That was 2 shower each plus other hand washing, dish washing, etc. I'd say you did about right. Now that I have 3 kids our next RV will absolutely have a much larger tank.
