My wife and I are going camping for a week, renting a TT. The site we've got doesn't have full hookups, so we're planning on using the tanks. (Specs below)My question is: How fast will the Gray and Black tanks fill up. I know this is subjective. But with 2 adults, maybe a shower every other day. Assume 'normal' toilet usage. ;) Would we last the week? Or would we need to file and/or drain mid-week? I have a potable water jug to refill the fresh water, but would want to get a Gray/Black water tank if we'll need to dump.PS. Sorry if I missed a post on this. Tried searching, but didn't find anything.Apex Nano BHSFresh: 50 galGray: 35 GalBlack: 35 Gal

The grey will fill up in one day, with a shower each. The black? Don't worry about it. You can make the 50 gallons last 2-3 days, if you conserve.

Navy shower each will last 3-4 days. Don't let sinks run. Use paper plates and disposable cups. Fresh should last week. Black should last most of week. If you let sink run while washing hands or like normal shower it will only last 1 day.

DW and I can EASILY go 10 days on that, and even with our daughter, hubby and 2 grandkids we go a week with the two 35 gallon grey and 35 gallon black and they still aren't completely full. We do need to fill the 40 gallon fresh a few times, We can shower on 1 gallon of water easily. When camping we find no reason to shower every day, a spit bath is fine and a quick shower every other day is more than adequate.And use paper plates for most meals, only need to wash dishes once/day It all boils down to how well you can conserve water useage.

You should always be using your tanks...with or without hookups. Keep the valves closed. Dump black when at least half full and use gray to flush the hose. With those size waste tanks, four days with conservative use.

If you use the campground facilities for showering and your fresh water for dish washing a couple of times a day then your grey tank should be OK for the week. Black tank should be ok, but toilet flushes will use a good bit of fresh water, so you might use the campground toilet to conserve your fresh water.
