Abe, I have trailered our boat into remote areas as well so understand where you are coming from.
To do the conversion on our porta pottie I bought a deck fitting for sewage pumpout and about 3 ft of hose. As well as a s/s tank vent and 3 ft of vent hose. The porta pottie had a threaded hole with a spout to empty it. I bought a couple of ABS fittings from Home Depot to thread into this hole and attach to the discharge pipe. I included a piece of 1.5" abs to reach the bottom of the tank to be sure it was empty when pumped out. The whole thing was less than $40 and I had to drill two holes in the boat. I no longer own that boat or I would take a few pictures for you. To dump the tank myself I just unscrewed the fitting and replaced the original pour spout.
I think most of the manufacturers sell a conversion kit to do the job for a few dollars more as most models are avialable in an msd version, just has a different fitting on the pour spout to take a hose.
Installing a deck pumpout will not prevent you from removing the tank from the boat and dumping it in your toilet at home.
I would also encourage you to join the www.TrailerSailors.org . They do a cruise in the NC every summer with 30 or more boats. Many of the members have sailed the area for years and can share a lot of information and advice that you will not get out of any guide book. I can also recommend a book called "A Well Favored Passage" . You might also google "Turners Little Current" for a local store happy to supply you with charts, books or ? We have launched from Little Current and found the town a delight, great marina, safe parking, highly recommended. You will love the area and want to come back.
good luck, Bob
