Next year do not leave the tank valve open all the time. Discharge the tank only when it has built up sufficient volume to keep the stuff in suspension. You also might try to use one of those 90 degree bend flusher extensions on the garden hose once in a while (when you have a couple nice days during the winter) to stir up the tank before you drain it.
We have a 2005 28' CCD and foound some construction debris that was jamming up our black water tank. Here are my two cents...
Go to the auto parts store and get yourself an inspection mirror - telescoping.
Then get a powerful flashlight - 3 D Maglite.
Put the mirror in the toilet with the valve open and shine the light either down the toliet hole or in through the black water dump valve. This should show you exactly what your problem is and then you can pick the appropriate solution from all of the above posts.
One thing we learned VERY quickly from tent camping, taking my Scout Troop camping, backpacking and now Streaming - a bad experience in the loo will ruin your trip. Also, you'll develop a tolerance for all things connected with poo!
Best of Luck!

Sorry, I'm just now noticing the second page of replies. Thanks for the additional info dwightdi and szy8xj.
Chuck, it seems I'm still in some denial that I'm not living in downtown Boston anymore. I'm living in a trailer park in Westborough for the winter, which is almost an hour west of Boston. I'd like to find a place closer to the city and preferably a bit more scenic for the summer. I won't be able to make the Salisbury rally, but I'll definitely be hitting one soon.
2 air,, too funny!!!!!! have found that a small amount of dishwashing liquid and a bag of ice ,, and pouring dishwater into the commode helps to maintain regularity also,,, keeping a good mix of liquids and solids keeps the slinky smilin,,,, donna
I had the same problem a couple of years back. I purchased some black tank additive that is called Digest. I put half the bottle in the tank and let it set overnight with the black tank value open. The next morning the tank had cleared and I have not had any problems since.
You may have to search the internet to find a place that sells this additive.

I search and found the correct name of the black tank additive. It is Unique RV Digest and there is a web site you can look at for more information.
