Add at least a few gallons after emptying & let her slosh going down the road for a few days. Repeat. The more water to slosh the better.


I think that a 10% fill will "slosh" around much better than a 90% one. a full tank won't do much sloshiing.

I think what you put in your black matters more than how much you have in there while going down the road. Sure you don't want to be 3/4 full, but at the same time, a one night stay with no dump and "normal" toilet usage shouldn't make your tanks terribly full. What you have to guesstimate about is how much you are putting in the tank relative to your usage of it.

What you want is a good bacteria & enzymatic treatment for your black tank. Ideally you need to view your black tank like a septic tank that doesn't have a drain field. Various bacteria and microbes are in their element consuming, breaking down, and "simplifying" human waste. This is their job and they are employed at a commercial level in city sewage treatment plans on a much larger scale to take what is basically toxic waste and make it much less toxic. You also have to consider if your tank is filled with aerobic or anaerobic bacteria. Aerobic bacteria naturally give off foul odors as they break down waste. To reduce odors you need more anaerobic bacteria, which do not give off odors as they break down waste, to overpower and replace the aerobic bacteria. Ever wonder where farts come from, well that is aerobic bacteria at work. Anyway, your treatment should be filling your tank with the anaerobic bacteria and enzymes which do their job while you are parked or while you are on the road.

Anyway, if you use a bacteria & enzymatic tank treatment, the contents of your black tank, with sufficient water placed there during flushes, and a reasonable tank temperature, should control odors and break down solid wastes and toilet paper into liquid. So, when you do get someplace you are staying long enough to hook up your sewer tube, what you are dumping is basically all liquid anyway. You'll get more complete tank dumps and will have less issues with tank sensors.

I'm not sure if forum rules allow me to link to a product maker, but I've been using their product and think it is excellent. DM me if you want details. I have no link or business operations with this company, just a happy customer.

In my 51 years of RVing I have never heard of a tank falling off of a motorhome.

I believe that there have been some mentions of folks here who had tanks fall. not a common occurrence however.

Just in transit I carry fresh water too. Sometimes I will go fully with no hookups even if provided. I just plug in if we need cool air. Makes for easy set-up and fast getaway.

This^^^ is my approach as well. If it's just one night. I'm trying to avoid set up. No need to dump or attach anything not toatlly necessary.
Depending on the circumstances I might remain hitched as well.
Usually I will unhitch to get fuel.
When overnighting or passing through,the less set up = less tear down and a quick departure.

3-4 days minimum to dump unless there are some serious mountain passes to cross.

When doing a series of short stays, I let the stuff slosh till it's about half full. My twist is that I then dump and flush as soon as I get on the next site...before things settle. Then, I close and wait till half full again. Been doing this lots of years and it works for me.

As we are travelers more than campers, I would have expected that our operation is more different than most. That does not seem to be the case. Our coach is very senior, bordering on antique and it only has one waste tank. That is about the same size as the potable tank. While both level gauges work (at the moment), the potable is a good indicator for the waste tank. That be the case, I like to find potable and a dump about every third day to give us some margin.
Then, there is another consideration. If Mary wants to wash her hair, she would rather have more hot water than we can normally manage.
These two sort of drive us toward an FHU for the third or forth night and we dump and take on potable then.

Unless you are bordering on overweight, your trailer should have no problem carrying the extra weight (yes, I have seen reports of tanks falling out, but it's extremely rare). Water only weighs about 8.5 lbs/gal...very little in the overall weight of your trailer (and absolutely zero add'l if you're using fresh water from your tank and not from city water hookup). You won't see a measurable difference in mpg, and you're unlikely to actually feel a difference in handling depending on the location of the tanks. Don't sweat it; they are "holding" tanks, and I have never seen an expiration date on how long they can "hold". Use them till they're 2/3-3/4 full, then dump. It's poo, not rocket science.
