I'm taking a break this winter, but before that I've been a solo full timer in my Voltage for the past 5 or 6 years. These are my averages...
If I'm traveling a lot... that is, changing locations every week or so... I always dump the tanks before leaving, so duration isn't an issue. But when I'm staying long-term at a single location (2 weeks or more), my routine changes a bit.
I find that I can usually go at least 2-to-3 weeks before needing to empty the black tank. It really just depends how often you "go", and how much water you use when flushing. (NOTE: do NOT be stingy with the water after a bowel movement... as that can cause clogging issues)
As for the grey tanks, it all depends on how often you move, and how you use them. If you don't already know... the forward tank is for the bathroom sink & shower, and the rear tank is for the kitchen and washer-dryer hookups in the garage.
Your shower will fill the front one pretty regularly, but I'd say you can go about a week or so. As for the rear tank.. if you don't have a washer-dryer unit, the only thing accumulating in it is the kitchen sink water, so you should be good for a good 2 weeks or so there.
As for myself, I do have a washer-dryer combo back there, and I run it every 2nd or 3rd day... and that fills the rear tank pretty quick.
So my routine when I'm staying long term is to simply keep both grey tank valves open, and allow them to drain freely. About 2 or 3 days before I know I'm going to dump the black tank, I'll close the front grey tank valve and allow it to fill with shower water, so I can then use it to flush the sewer hose after dumping the black tank.
That said... beware, there is a risk leaving those valves open. I've read & heard of horror stories where the campground had a catastrophic sewer issue, and back-pressure caused sewage to run back up through the hoses, and into the rig. Whether that's true or not, I can't say... but in all my years of camping & RV'ing, I've never personally seen it, or know of any first hand knowledge where it happened to someone else. But the putting the information out there for ya.
That's my experience... your usage may vary.
