Most of the "Blue Boy", "Gray Boy" etc... Black water portable tanks can be
towed behind the truck by a handle that drops over the ball on your
hitch... If you have switched to Hensley, you can carry a little trailer
ball hookup that will pull the tank ... just go slow...
The bigger tanks are easier to work with due to the addition of valves and
extra hose connections... just more of a problem to haul along...(take up a
lot of space)
The paper you buy in the grocery can be easily tested by putting a couple
of squares in a glass of water and watch for the time to dissolve into
something less than a sheet... you can compare it with a couple of sheets
of RV type paper for time to dissolve and if it does not compare , don't
use it ... it won't dissolve in the chemical much better than it does in
the water...I have found Scott to be as good as the Camping World stuff....
As to chemical or enzyme... they both work and as I recall, just not
together... the chemicals kill the enzymes... I used a bottle of the enzyme
after buying it at an RV show and it worked just fine... when the bottle
ran out, I switched back to the chemicals because they were available where
I happened to be...
Among the good advice I have noticed is don't let the tank dry out... and
don't leave the valve open at the camp site... let the tank fill up and use
enough water to keep the system working... trying to get a tank flowing
that has been allowed to cake up is no simple task... lots of physical work
to break up what ever is keeping the valve plugged and lots of mess when
you finally break it loose..and you lose a lot of capacity by having a mass
that doesn't go out the valve in the tank.... much easier to keep the tank
working ....
You can buy a fitting for the faucet in the bathroom sink that will let you
use a short piece of hose with a wand attached that is sold at most RV
stores that will flush out the tank through the foot valve in the base of
the toilet... keeps from having to take out screens, drag out a big hose
and find a faucet you can attach the hose to...The convenience is worth
more than the cost of the wand... I have noticed a lot of the new trailers
are fitted with a flush fitting that makes the use of a hose on the outside
more convenient...
As someone pointed out... not a big deal, just part of camper life...
