My small class B RV has the toilet in the "main room". Does anyone make a
kit that can put a vacuum on the black water tank so the obvious odors don't
travel throughout the cabin? A vent in the roof would still make the odor
travel in the cabin.
A friend suggested a kayak skirt around the toilet to trap the odor but it
still has to be undone to get off the toilet. If I could vent the tank I
could pressurize the skirt and everything would be hunky dory.
I'm not getting a bigger RV, the gas expense is too much for me. My class B
is dandy.Thanks much!

West Marine makes a nice portable toilet seat that sits on top of a
five-gallon bucket. What you do is line the bucket with a sturdy garbage
bag. You do your business and then you tie the bag up tightly. Then toss
it in the nearest trash receptacle. Don't just toss it out the window
like some people do with their disposable baby diapers, though.
You can then empty your black water tanks and fill it with fresh water
and some deodorant.

We have a couple of those on my Dad's Swan68 sailing yacht and just toss
the contents overboard when more than three miles offshore. It's legal
to do so. Holding tank stench is a problem everywhere even on the
larger RVs and yachts.

Hard to believe it's legal to toss a crap in someone's dumpster. Isn't it
bio-hazardous waste??
Nevertheless, we bought one of those comfy portable toilets

now)
and a quick-setup outhouse which doubles as an outdoor shower house

the girls like to pee in the indoor toilet, especially at night, but
everyone appreciates keeping the #2's outside!

Also that pine scented liquid camping soap sold at WalMart.
It may cleanse the body but does it cleanse the soul?
Amen!!

A properly operating black water tank and toilet should not let any gases
get into the living area. There is something wrong with your unit. First
check the vent stack for blockages.

Unless he's talking about when the toilet is flushed. At that point you
have a tank with two openings to the outer air--the vent stack and the
toilet. Air--and smell--is going to move out the one with the LOWEST air
pressure. If the roof vent in the toilet area is blowing outwards I can
assure you the air--and smell--is going to move thru the cabin to the
roof vent. I know several people that have reversed the fan in the
toilet area to blow inwards to reduce this problem.

Suppose I put a blower in line with the exhaust/vent stack for the tank so
it causes a vacuum in the tank. Is such a thing made? That might be a great
solution!

The wife gets real pissy when I use the toilet without the overhead fan.
There is a strong negative pressure in the john when this is on. I have yet
to notice any toilet odors from when I flush. The flush gate is only open a
fraction of a second.

Might look at this:
< http://www.campingworld.com/browse/skus/index.cfm/Outdoor-and-RV-
Accessories/RV-Maintenance/Sanitation--Sewer/RV-360-Sanitation-
Vent/skunum=26177 >
(search for "sanitation vent" on campingworld.com)
It creates a small vacuum assuming the wind is blowing or the vehicle is
moving. Haven't ever tried it myself but I have heard reports that it
does work.
If you have a ceiling fan see if you can have it blow IN when the toilet
is being flushed--that may help prevent the smelly air from moving into
the room (works in a seperate toilet area--not sure it can make enough
difference in a class B if the toilet area isn't totally enclosed).
